GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI98240 is a portable printing and logging microprocessor-based pH/ ORP/temperature meter.
HI98230 is a portable printing and logging microprocessor-based pH/ temperature meter.
HI98230 and HI98240 are supplied with an exclusive HANNA (smart) amplified pH/temperature electrode with DIN connector. The electrode has an internal memory for storing calibration data.
All pH measurements are automatically compensated for temperature (ATC). The instrument housing is made of rugged, lightweight material, making it truly portable.
Five memorized buffers (4.01, 6.86, 7.01, 9.18 and 10.01pH) and wrong buffer recognition technology make calibration simple and error free. One or two-point calibration is possible.
The meters are also equipped with a stability indicator and backlight feature for comfortable reading even in excessively dark environments.
A user friendly interface provides clear messages regarding errors, functions and more.
The GLP features provide a guarantee of data consistency. Measurements can be performed with lab-grade precision in the field as
well as in the laboratory.
32
An alarm time-out is available to alert the user if too much time has elapsed since the last pH calibration and that re-calibration may be required.
The meters provide a controlled access to calibration and GLP settings through a password protection method.
The Battery Error Preventing System (BEPS) recognizes batteries levels as they become weaker.
To prolong battery life, the backlight and printing features are disabled when the batteries are getting low; "LOBAT" indication is displayed on LCD to warn the user of this condition. However, the meter continues to measure correctly even when the low battery indication is displayed. The meter automatically switches itself off when the batteries are too weak to support proper function.
The meters are equipped with an internal lithium battery that powers the clock circuit even in the absence of power supplies.
For long term field and lab applications, these meters can be connected to a 12VDC adapter.
When in logging mode, the meter stores the measurements in memory at a user selectable interval from 1 to 180 minutes. This information can be retrieved at a later time and also printed.
HI98230 and HI98240 also allow the transfer of stored data to a computer via the HI9200 infrared transmitter connected to the computer RS232 port.
In addition, the meters allow the user to enter an ID code to uniquely identify the instruments.

TAKING TAKING
Connect the pH electrode with the built-in temperature sensor to the meter and press ON/OFF to power on the instrument.
The meter automatically checks that the stored calibration data correspond to the connected electrode. The pH range will be auto­matically set.
If the pH electrode is not connected, the LCD will display the "no probe" message and then dashed lines in place of the readings.
For greatest accuracy, it is recommended to set the Calibration alarm time-out to the value appropriate to your specific use and calibrate the meter as soon as the "DATE" warning symbol blinks on LCD (see page 25).
To take pH measurements, simply submerge the bottom 4 cm (1½") of the electrode in the solution to be tested, stir gently and allow for the reading to stabilize. The tem­perature is displayed in the lower LCD without the decimal digit.
The pH reading is automatically temperature compensated (ATC). If the pH reading blinks it means that the electrode is "dead" and
readings are not reliable. By continuously pressing the RANGE key the follow-
ing information will be displayed on the upper LCD:
• mV reading (HI98240 only) The mV scale is autoranging, when the
reading is outside ±400mV the decimal point automatically disappears.
• Temperature reading
If the temperature reading is out of
range, a dashed line will be displayed.
• Date
• Time
Pressing RANGE again, the meter returns to pH reading. If measurements are taken successively in different samples, it is
recommended to rinse the electrode thoroughly with deionized water or, if not available, tap water first and then with some of the next sample to condition the electrode before immersing it in the sample.

H CALIBRATION PROCEDUREH CALIBRATION PROCEDURE
For better accuracy, it is recommended to calibrate the instrument frequently. For a faster procedure, it is possible to calibrate at 1 point, but it is always a good practice to calibrate at 2 points.
A two-point calibration can use any combination of the three sets:
(4.01) (6.86 / 7.01) (9.18 / 10.01)
Only one value from each set can be selected. For example if pH
7.01 is used as first point, it will not be possible to select pH 6.86 as the second point.
In the case of a two-point calibration, in the acidic range (from 0 to 7 pH) use pH buffer 7.01 (or 6.86) as the first solution and pH buffer
4.01 as the second solution. If testing in the alkaline range (from 7 to 14 pH), use pH buffer 10.01 (or 9.18) as the second solution.
Due to electrode conditioning time, the electrode must be kept immersed a few seconds to stabilize. The meters are equipped with a stability indicator (a blinking "S") and the user will be guided step by step with easy indications on the LCD during the calibration. This will make the calibration a simple and error-free procedure.
pH CALIBRATION
1. Rinse the electrode with a portion of the first calibration buffer or clean water. Dip the bottom, 4 cm (1½"), of the electrode into a beaker containing the solution.
2. Press ALT and CAL while meter is not printing nor logging.

The temperature sensor is integrated in the pH electrode. Secure the connection of the electrode to the top of the meter and
immerse it in the sample solution (allow a few minutes for the temperature to stabilize). Press ON/OFF to power on the instrument.
The temperature is displayed in the lower LCD without the decimal digit during pH and mV measurement. To display the temperature reading with decimal digit, press the "RANGE" key to get into the C or F mode. The temperature value and the "C" or "F" symbol will be displayed on the upper display.
Note: To choose between "C " and "F" unit, enter the setup code 70. Note: If temperature measurement is out of range the LCD will
display "- - - -".
3. User is prompted to enter password if it has been set to a value different from 0000, otherwise skip to step 6.
4. Enter the password with the arrow keys.
5. Press ALT and CFM to confirm the password or ALT and CAL to exit.

6. If password is correct or not set, the meter will display "7.01pH" on the up­per LCD and "b1" on its lower part; if wrong, it will return to measurement mode without any message.
7. Select the first buffer solution value with Ç and È if necessary.
8. When the "S" symbol blinks in the lower LCD, the reading is stable and calibra­tion can be confirmed.
Note: It is possible to display temperature pressing the RANGE key.
9. Press ALT and CFM to confirm the first buffer.
10.If everything is satisfactory the LCD will display CALC and then the second buffer value expected will be displayed. If a wrong solution or electrode has been used or if the buffer is polluted, "WRONG" will be displayed to alert the user.
11.If only a single point calibration is re­quired, press ALT and CAL to leave the calibration mode and maintain the previ­ous slope calibration. "CALC" will be displayed for a few seconds. The instrument then checks the electrode parameters and ad­vises user of abnormalities by "old probe" and "dead probe" indications.
12. Press Ç or È to select the second buffer value. The "b2" symbol will be fixed on lower display.
13.Rinse the electrode with some of the second buffer solution or clean water.
14.Dip the bottom, 4 cm (1½"), of the electrode in a beaker containing the second buffer.
15.When the "S" symbol blinks in the lower LCD, press ALT and CFM to confirm the second calibration point.
16."CALC" is displayed on the upper LCD for a few seconds and the meter is cali­brated and ready to use.
17.If the buffer is wrong or the electrode is defective, "Err" will be displayed to alert the user. When calibration is completed, the instrument checks the electrode pa­rameters and advises the user of abnormalities by "old probe" and "dead probe" indications (in these cases, repeat the calibra­tion with fresh buffers).
CALIBRATION ERROR MESSAGES
If the "old probe", "dead probe" or "Err" messages are displayed during calibration, check your electrode by following the conditioning and maintenance procedure and repeat calibration. The pH electrode might have to be replaced if calibration cannot be successfully performed.
CALIBRATION DATA PRINTOUT
It is possible to print the characteristics of the electrode as a recording of the electrode performance over time by setup code 12 (see "Printing GLP data").
This will consist of: date, time, the offset characteristic of the pH electrode in mV, the slope characteristic in mV/pH and the pH buffer solution values.
If calibration has been performed with an "old" pH electrode the first line is: pH **
If calibration has been performed with a "dead" pH electrode the first line is: pH
If the calibration alarm time-out is expired, the "Dt" string will be printed beside the date.
Note: A dashed line indicates that the calibration has never been
--
performed.

PRINTING / LOGGING FUNCTIONPRINTING / LOGGING FUNCTION
PRINTING / LOGGING FUNCTION
PRINTING / LOGGING FUNCTIONPRINTING / LOGGING FUNCTION
Two different modes to print / log data are available:
1. Timed logging; samples are stored and printed (if print function is active) at fixed time intervals. Data are stored in the lots 01 to 16.
2. Log on demand; samples are stored and printed (if print function is active) when the LOG key is pressed. Data are stored in the lot 00. It's possible to perform the Log on demand either in normal mode or in Timed logging mode.
It is possible to switch from logging without printing to logging with printing in two ways:
• set the function code 02 to "On" to enable printing, to "Off" to disable printing
• press ALT and PAPER to toggle between printer enabled and printer disabled while in Timed logging.
TIMED LOGGING MODE
To start Timed logging, press ALT and LOG. The lot number will be displayed for a few seconds then the LOG symbol will appear on LCD and if printer is enabled a first set of data will be printed. The "LOG" symbol will be fixed if printer is enabled and will blink if printer is disabled.
The printout provides the following information:
a - Lot number b - Logging interval c - Date (only for the first printed
sample of the lot or of the day) d - Sample number e - Time f - Readings.
To print the mV reading instead of pH, press ALT and LOG after entering the mV range (mV reading available in HI98240 only).
If no keys are pressed, the meter enters standby mode to prolong the battery life and only the "LOG" indication will be visible on LCD. While logging, during the sleep mode, the last logged reading will appear briefly on the LCD. To reactivate the LCD press ON/OFF.
TO STOP LOGGING
In order to stop the recording mode, press ALT and LOG keys (press ON/OFF first, if meter is in sleep mode).
A last printout reporting the number of logged samples (e.g. S.00009) will be pro­duced if printer is enabled.
Notes:
• It is recommended to use the adapter during logging in printing mode, especially when many printouts are going to be taken.
• Before proceeding with logging with printing, make sure there is enough paper for your measurements. When the paper is finished the meter will not advise the operator and the printouts could be lost. If this happens, data will continue to be stored in memory, and it is always possible to print the data at a later time through setup code 00.
• It is possible to insert a new paper roll during logging session (see page 29)
• Once in the logging mode, the interval cannot be changed. Exit the logging mode first (pressing the ALT and LOG keys) to set a new interval.
• If the LOG key is pressed while in logging with printing mode, a printout is produced without affecting the running sample num­ber and the value is stored in Log on demand area.
LOW BATTERY CONDITION
Printout is automatically disabled when battery charge weakens. The last message "Stop log" will be printed and data will continue to be stored in memory with the LOG and LOBAT symbols blinking on LCD. If the user attempts to enable the printer while in low battery condition the message "bAtt" will appear for a few sec­onds on the LCD.
Note: When an external adapter or new batteries are connected, the
printing must be manually enabled in order to return to logging with printing mode.
LOG ON DEMAND
In measuring or Timed log mode, press LOG to store the current reading. The LCD will display
2322
"Stor log" and the value will be stored in the lot 00 (log on demand data area). If the printing function is enabled, a printout is also produced providing the following information:
a - Date b - Sample number c - Time d - Readings
Note: When the Log on demand data area is full and the LOG key
is pressed, the sample will not be stored and the LCD will display "FULL". In this case it is necessary to delete the Log on demand data to proceed.
TO RETRIEVE LOGGED DATA
Logged data stored in the EEPROM can be viewed on LCD or printed. HI98230 and HI98240 also allow the downloading of logged data to PC for reproduction, storage and elaboration (e.g. graph drawing).
To view or print logged data see "TO SCAN LOGGED DATA" on page 11. To download data to PC see "DATA TRANSFER TO PC" on page 27.

LCD BACKLIGHT
The LCD can be illuminated to allow the user to see the readings even in dark environments. This feature can be enabled/disabled pressing the ALT and LIGHT keys.
If the LCD backlight feature is enabled, the LCD remains illuminated until the feature is disabled pressing the ALT and LIGHT keys. The LCD backlight can be disabled in order to save power and it is automatically disabled when batteries are in low battery condition.
Note: When an external power supply is connected to the instru-
ment, the backlight is not automatically enabled.
Note: When LOBAT appears on LCD it is not possible to enable
backlight. If the user attempts to enable the LCD backlight in low battery condition, the meter will show "bAtt" on LCD.
Real Time Clock (RTC)
The instrument has an internal Real Time Clock (RTC) circuit with a backup lithium battery. This allows the meter to update time and date even when both batteries and external power adapter are disconnected.
GOOD LABORATORY PRACTICE (GLP)GOOD LABORATORY PRACTICE (GLP)
GOOD LABORATORY PRACTICE (GLP)
GOOD LABORATORY PRACTICE (GLP)GOOD LABORATORY PRACTICE (GLP)
GLP is a set of functions that allows the storage or retrieval (when necessary) of data regarding the maintenance and status of the electrode. The pH electrodes have a built-in EEPROM in which calibration data are read at start-up and stored after calibration.
HI98230 and HI98240 can automatically analyze the data and advise the user if a problem is found with a clear message.
PROBE LIFE VERIFICATION
At the end of calibration, the meter checks if offset is between -30 and +30mV and the slope between 53.5 and 62 mV/pH. If the values are not within these parameters, the message "old probe" scrolls across the LCD and the symbol ** is reported in the Last Calibration Data. The electrode is still working, but it will be necessary to perform a cleaning procedure (see electrode cleaning and maintenance paragraph) or replace it.
If the offset is outside the -60 and +60 mV range, the "dead probe" message will scroll across the LCD and the symbol -- is reported in the Last Calibration Data. The readings will blink to warn the user that they are not reliable.
LAST CALIBRATION DATA
Last calibration data are stored automatically after a successful calibration. Data can be displayed or printed through the appropri­ate setup codes (10 to display pH data; 11 to display mV data; 12 to print pH and mV data); mV data are available in HI98240 only.
ELECTRODE IDENTIFICATION
At start-up the meter checks if the electrode is inserted. If not the message "no probe" scrolls across the LCD and a dashed line will be
display in place of the reading. Each printout will have a "" symbol
on the pH line. If the meter detects a "dead probe" the reading will blink. The meter checks the electrode only at start up. If an electrode
replacement is needed, turn the meter off before disconnecting the electrode. Then replace the electrode and turn the meter on again.
CALIBRATION ALARM TIME-OUT
The calibration alarm time-out is available only for pH calibration. It is possible to set (through setup code 13) the number of days
before the next required calibration procedure. User can set a value from 00 (disabled) to 99 days. The default value is 00.
2524
The meter checks if the time-out time has expired every time it is turned on. In the case the time has run out, the message "Cal date" scrolls across the LCD. The "DATE" sym­bol will blink as a reminder.
Alarm time-out is also signaled in the GLP data printout through the "Dt" symbol after the calibration date.
GLP AND RS232
All the GLP data can be retrieved from a PC through the RS232 communication feature. The calibration data are transferred to the computer along with measurement data for analysis and verification (see "Data transfer to PC" paragraph).
FAULT CONDITIONSFAULT CONDITIONS
FAULT CONDITIONS
FAULT CONDITIONSFAULT CONDITIONS
HI 98230 and HI 98240 are factory programmed to automatically diagnose a fault and to display error codes on the LCD.
PRINTER ERROR
Whenever a printer fault condition is detected, the printer stops and the message "Printer error" scrolls across the upper LCD with the error code (see below) fixed on the secondary one.
1 = Motor locked 2 = Printer clutch jammed 3 = Selection lever fault
I2C BUS ERROR
In case of an I2C bus fatal error due for example to a defective EEPROM or RTC, the message "Serial bus error" keeps scrolling across LCD from right to left indefinitely. Meter should be returned for repair (see warranty section).
DATA TRANSFER TO PCDATA TRANSFER TO PC
DATA TRANSFER TO PC
DATA TRANSFER TO PCDATA TRANSFER TO PC
HI98230 and HI98240 contain infrared transmitting circuitry. Ensure there is not any logging process active. Press RANGE to set the meter to time or date mode and simply place
your data-logger on a HI9200 Infrared Transmitter (ensuring that the two infrared LEDs are placed on top of each other) and the memory content can then be downloaded to your PC through the HI9200's RS232 port. Just ensure that baud rate on instrument (setup code 50) and on PC downloading program are set to the same value.
During the data transfer the instrument displays the message "r 232".
To stop communication, press RANGE to display the reading (pH or mV or temperature) or take the meter out of the transmitter when it is not displaying "r232".
Using the HI9200 Infrared Transmitter, all recorded data can be fed to your Personal Computer for easy reproduction, storage or elabora­tion without the interference of cables or cords between the meter and the transmitter.
Data transmission from the instrument to the PC is now much easier with new HI92000 Windows® compatible application software offered by Hanna Instruments.
HI92000 allows to use the powerful capabilities of most spread sheet programs (e.g. Excel©, Lotus 1-2-3©). Simply open the file down­loaded by HI92000 from the spread sheet program and then it is possible to make any elaboration available with software (e.g. graphics, statistic analysis).
User friendly, HI92000 offers a variety of features and has an on-line­help to support the user throughout any situation.
To install HI92000 you need a 3.5" drive and a few minutes to follow the instructions conveniently printed on the disk label.

Logged data are stored in the internal EEPROM and are retained even if batteries and external power are disconnected.
MEMORY CAPACITY
• 1500 data samples which are divided into 16 lots (lots 01 to 16)
• 100 data samples for the Log on demand (lot 00).
TIMED LOG (lots 01 to 16)
Each time a new logging period starts, it automatically starts from the next available lot. If the last lot was the 16th, the new logging period restarts from lot 01 overwriting previously logged data.
When Timed logging memory is full, the meter overwrites the oldest lot data progressively reducing the old lots. In this case the starting time, date and the dimension of the old lot are updated.
Note: The oldest lot data are erased without any warning message. Note: Timed logging memory can be entirely erased through the
setup code 06.
If the meter is powered only by the external power supply and there is a temporary power black out during logging, when power returns, the logging continues normally if no samples have been lost, other­wise the current lot is ended and a new lot starts. If printer is enabled, the "...Stop..." message will be printed. In any case, during scrolling the former lot will be preceded by the "Interrupted Lot" message and the latter by "Continuation Lot" to indicate the interruption.
LOG ON DEMAND (Lot 00)
When Log on demand data area is full the meter shows the "FULL" message to warn the user that the data are not stored in memory. Erase the memory area through setup code 05 to continue logging data on demand.
TO CHANGE THE INK CARTRIDGE
When printouts become faint, it might be necessary to change the ink cartridge. Contact the nearest Hanna authorized center.
TO INSERT THE PAPER ROLL
HI98230 and HI98240 use plain paper rolls 38 mm width. To insert
a new roll is very easy. Open the paper cover pulling it gently and take the cylinder away.
Insert the paper edge in the printer slot and feed the printer by pressing the PAPER key.
Allow about 5 cm (2") of paper to exit from the printer and replace the paper cover.

When the batteries are inserted and no power adapter is connected, the meter can recognize different batteries charge levels.
1. Fully charged batteries. The backlight and printer can be enabled.
2. Weakening batteries. "LOBAT" symbol blinks on LCD. The backlight and printer are automatically disabled and it is not possible to enable them until new batteries are inserted or an external power adapter is connected.
3. Weak batteries. "LOBAT" symbol stays still on lower LCD. Backlight and printer are disabled and meter can work for about 20 hours. If in Timed logging mode with the power down function enabled this time can be longer.
4. Dead batteries. LCD shuts off. The instrument stops working to avoid any erroneous readings.
Note: It is not possible to enable backlight and printer when the
instrument is in a low battery condition. If the user attempts to enable these functions without re­placing the batteries or connecting the external power adapter, the meter will show "bAtt" on LCD.
Battery replacement must only take place in a non hazardous area, by using 1.5V alkaline AA type batteries.
In order to replace run down batteries, simply remove the two screws on the rear cover of the instrument and replace the four 1.5V AA batteries, while paying at­tention to the correct polarity.
A 12VDC power adapter can also be used to power the unit (see accessories).
Note: The instrument uses the following configuration.
It is recommended to purchase the Hanna HI710005 and HI710006 voltage adapters that use the proper polarity configuration.
However, HI 98230 and HI 98240 can also be used with other adapters. In this case, remember to check the correct polarity of your adapter before connecting it to the meter.

Since the resistance of the pH electrode is in the range of 200 Mohm, the current across the membrane is in the pico-Ampere range. Large currents can disturb the calibration of the electrode for many hours.
For these reasons high humidity environments, short circuits and static discharges are detrimental to a stable pH reading.
The pH electrode's life also depends on the temperature. If constantly used at high temperatures, the electrode life is drastically reduced.
Typical Electrode Life Ambient Temperature 1- 3 years 90 °C Less than 4 months
120°C Less than 1 month
High concentrations of sodium ions interfere with readings in alkaline solutions; the pH at which the interference starts to be significant depends upon the composition of the glass. This interference is the alkaline error and causes the pH to be underestimated. Hanna's glass formulations have the indicated characteristics.

Note: to prevent damage to the electrode, remove it from the sample
before turning the meter off. If the meter is OFF, detach the electrode from the meter before
immersing the electrode in the storage solution.
PREPARATION
Remove the protective cap. DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal with pH-electrodes and they will disappear when rinsed
with water. During transport tiny bubbles of air may form inside the glass bulb.
The electrode cannot function properly under these conditions. These bubbles can be removed by "shaking down" the electrode as you would do with a glass thermometer.
If the bulb and/or junction are dry, soak the electrode in HI70300 or HI80300 Storage Solution for at least one hour.
For refillable electrodes:
If the fill solution (electrolyte) is less than 1 cm (½") below the fill hole, add HI7082 or HI8082 3,5M KCl Electrolyte Solution for double junction or HI7071 or HI8071 3,5M KCl+AgCl Electrolyte Solution for single junction electrodes.
For a faster response unscrew the fill hole screw during measurements.
For AmpHel electrodes:
If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.
MEASUREMENT
Rinse the electrode tip with distilled water. Immerse the tip (4 cm /1½") in the sample and stir gently for
approx. 30 seconds. For a faster response and to avoid cross contamination of the samples,
rinse the electrode tip with a few drops of the solution to be tested, before taking measurements.
STORAGE
To minimize clogging and ensure a quick response time, the glass bulb and the junction should be kept always moist and not allowed to dry out.
Replace the solution in the protective cap with a few drops of
HI70300 or HI80300 Storage Solution or, in its absence, Filling Solution (HI7071 or HI8071 for single junction or HI7082 or HI8082
for double junction electrodes). Follow the Preparation Procedure above before taking measurements.
Note: NEVER STORE THE ELECTRODE IN DISTILLED WATER OR DRY.
PERIODIC MAINTENANCE
Inspect the electrode and the cable. The cable used for connection to the meter must be intact and there must be no points of broken insulation on the cable or cracks on the electrode stem or bulb. Connectors must be perfectly clean and dry.
If any scratches or cracks are present, replace the electrode. Rinse off any salt deposits with water.
For refillable electrodes: Refill it with fresh electrolyte (HI7071 or HI8071 for single junction or
HI7082 or HI8082 for double junction electrodes). Allow the electrode
to stand upright for 1 hour. Follow the Storage Procedure above.
CLEANING PROCEDURE
General Soak in Hanna HI7061 or HI8061 General Cleaning Solution for approximately 1 hour.
Removal of films, dirt or deposits on the membrane/junction:
-
Protein
-
Inorganic
-
Oil/grease
IMPORTANT: After performing any of the cleaning procedures rinse the electrode thoroughly with distilled water, drain and refill the reference chamber with fresh electrolyte (not necessary for GEL filled electrodes) and soak the electrode in HI70300 or HI80300 Storage Solution for at least 1 hour before taking any measurements.
Soak in Hanna HI7073 or HI8073 Protein Cleaning Solution for 15 minutes.
Soak in Hanna HI7074 or HI8074 Inorganic Cleaning Solution for 15 minutes.
Rinse with Hanna HI7077 or HI8077 Oil and
Fat Cleaning Solution.
TROUBLESHOOTING
Evaluate your electrode performance based on the following possibili­ties:
• Noise (Readings fluctuate up and down) could be due to:
- Clogged/Dirty Junction: Refer to the Cleaning Procedure above.
- Loss of shielding due to low electrolyte level (in refillable
3332
electrodes only): refill with fresh HI7071 or HI8071 for single junction, or HI7082 or HI8082 for double junction electrodes.
• Dry Membrane/Junction: Soak in HI70300 or HI80300 Stor­age Solution for at least 1 hour.
• Drifting: Soak the electrode tip in warm Hanna Solution
(HI7082 or HI8082) for one hour, then flush the tip with distilled water. Refill with fresh HI7071 or HI8071 for single junction electrodes, and HI7082 or HI8082 for double junction electrodes.
• Low Slope: Refer to the cleaning procedure above.
• No Slope: Check the electrode for cracks in glass stem or bulb
and replace the electrode.
• Slow Response/Excessive Drift: Soak the tip in HI7061 or HI8061 Hanna Solution for 30 minutes, rinse thoroughly in
distilled water and then follow the Cleaning Procedure above.
