GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI 98140, HI 98150 and HI 98160 are state-of-the-art, hand held pH
meters, designed to provide laboratory results and accuracy under harsh
industrial conditions.
These instruments are provided with a series of new diagnostic features
which add an entirely new dimension to the measurement of pH, by
allowing the user to dramatically improve the reliability of the measurement:
• 7 automatically recognized pH buffers (pH 1.68, 4.01, 6.86, 7.01,
9.18, 10.01 and 12.45) for calibration
• pH calibration up to three (HI 98140) and five (HI 98150 &
HI 98160) calibration points
• Custom calibration by entering up to two custom buffers
• Messages on the LCD to guide the user through instrument operation
• Diagnostic features to alert the user when the electrode needs cleaning
• Outside Calibration Range warning
• Monitoring of the electrode’s aging
• User-selectable “calibration time out” to remind the user when a
new calibration is necessary.
HI 98140 and HI 98150 works with SMART amplified electrodes. These
electrodes incorporate a chip, which stores the calibration data performed
with a specific instrument.
3
When the SMART electrode is attached to the meter again, it is
automatically recognized. This technology allows the operator to
optimize time and efficiency with unsurpassed safety. It avoids erroneous
measurements taken in the event the pH electrode is substituted after
calibration. This series of electrodes also incorporates a temperature
sensor, eliminating the need for an additional temperature probe.
They also offer an extended temperature range from –20 ºC to 120 ºC
(–4 ºF to 248 ºF).
These instruments can also measure with ORP electrodes (HI 98150 &
HI 98160), thanks to their capability to measure mV with a resolution
up to 0.1 mV.
Other features include:
• Relative mV measurements (HI98150 & HI 98160)
• Log on demand (500 samples)
• Auto Hold feature, to freeze first stable reading on the LCD
• GLP feature, to view last calibration data for pH, Rel mV
• PC interface
The Battery Error Preventing System (BEPS) detects when the batteries
become too weak to ensure reliable measurements.
The backlight feature is automatically disabled when batteries are
getting low and a clear indication is displayed 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.
In addition, the meters allow the user to enter an ID code to uniquely
identify the instrument.

OPERATIONAL GUIDEOPERATIONAL GUIDE
OPERATIONAL GUIDE
OPERATIONAL GUIDEOPERATIONAL GUIDE
INITIAL PREPARATION
The instrument is supplied complete with batteries. For placing the
batteries inside the meter, see page 33.
To prepare the instrument for use, connect the pH electrode to the input
socket on the top of the instrument. For HI 98160 connect the temperature
probe to the temperature socket too. The temperature probe is used in
conjunction with the pH electrode for pH temperature compensation, but
it can also be used independently to take temperature measurements. If
the probe is disconnected, temperature can be set manually with the
ARROW keys (see page 9 for details).
Turn the instrument ON by pressing
On/Off.
At start-up the display will show all
the available segments for a few seconds
(or while the button is held), followed
by the percentage indication of the
remaining battery life. The meter is
now ready to operate.
After measurement switch the instrument off, remove the electrodes,
clean the electrode and store it with a few drops of HI 70300 storage
solution in the protection cap.
Note: In order to avoid error conditions when working with SMART
electrodes, be sure the electrode is connected before the instrument
is turned ON and is disconnected only after the instrument is
turned OFF.
The auto-off feature turns the instrument off after a set period (default
20 min) to save battery life. To set another period or to disable this
feature, see SETUP menu on page 21.
The auto-off backlight feature turns the backlight off after a set period
(default 1 min). To set another period or to disable this feature, see
SETUP menu on page 21.
pH MEASUREMENTS
To take a pH measurement remove the electrode
protective cap and simply submerse the tip of the
electrode (3cm/1¼”) and the temperature probe
(HI 98160 only) into the sample to be tested. If
necessary, press Range until the display changes to
the pH mode. Allow the electrode to equilibrate and
reading to stabilize (hourglass symbol will turn off).
8
3cm
(1¼”)
The LCD will show the pH measurement
together with the temperature of the
sample. In order to take more accurate
pH measurements, make sure that the
electrode and instrument is calibrated (see
page 11 for details).
Hanna recommends to keep the pH electrode wet and to rinse throughly
with the sample before measurements.
The pH reading is directly affected by temperature. In order for the
instrument to measure the pH accurately, temperature must be taken
into consideration. If the sample temperature is different from the
ambient temperature, allow a few minutes for the pH electrode to reach
thermal equilibrium.
The HI 1618D pH sensor contains an integral temperature sensor so the
pH reading is automatically temperature compensated (ATC) on the
HI 98140 and HI 98150. If the temperature is out of range (due to
temperature sensor failure) these instruments will enter MTC mode and
permit temperature values to be set manually using the ARROW keys.
To use the instrument's Automatic Temperature Compensation feature for
HI 98160, connect and submerse the temperature probe into the sample
as close to the electrode as possible and wait for a few seconds.
If manual temperature compensation (MTC) is desired, the
temperature probe must be disconnected from the instrument
(HI 98160 only).
The display will show the default temperature
of 25 ºC, the last measured temperature
reading, or the last set temperature, with
the “ºC” (or “ºF”) tag blinking.
The “MTC” tag and arrow symbols
light up on the LCD to indicate that the
instrument is in MTC mode and the arrow
keys can be used to enter the desired temperature value.
Note: When in MTC the user can press and hold the ARROW keys to
set the measurement temperature. The instrument will start
incrementing/decrementing the temperature value. The instrument
keeps measuring using the MTC value for temperature compensated
pH and the display is updated.
ORP MEASUREMENTS (HI 98150 & HI 98160 only)
To perform ORP measurements, connect an optional
ORP electrode (see Accessories section) to the instrument
and turn it ON. If necessary, enter the mV mode by
pressing Range until the display changes to mV.
3cm
(1¼”)
9
Submerse the ORP electrode tip (3cm/1¼”)
into the sample to be tested and wait a few
seconds for the reading to stabilize.
Measurements within the ±699.9 mV range
are displayed with 0.1 mV resolution, while
outside this range the resolution automatically
switches to 1 mV.
The “ATC” (or “MTC”) tag is turned off because ORP measurements are
not temperature compensated.
For accurate ORP measurements, the surface of the electrode must be
clean and smooth. Pretreatment solutions are available to condition the
electrode and improve its response time (see Accessories section, page 41).
RELATIVE mV MEASUREMENTS (HI 98150 & HI 98160 only)
To enter Relative mV mode, press 2nd then
Mode while in mV measurement mode. The
relative mV reading will be displayed on the
primary LCD and the current temperature
value on the secondary LCD.
Relative mV is an operation mode in which the
displayed electrode potential (mV) can be
changed by means of a calibration control
offset. See page 17.
TEMPERATURE MEASUREMENTS
The pH electrodes used for HI 98140 and HI 98150 also
include an integral temperature measuring element.
For HI 98160 connect the HI 7662 temperature probe to
the appropriate socket, submerse the temperature probe
into the sample and permit it to equilibrate by watching
the reading on the secondary LCD.
If the temperature is out of range, or the temperature probe is not
connected (HI 98160 only) the instruments will display the last in
range temperature reading and enter MTC mode (see page 9).
Note: The temperature can be displayed in Celsius degrees (ºC) or in
Fahrenheit degrees (ºF) (see SETUP for details, page 21).
BACKLIGHT FEATURE
The instrument is provided with a Backlight feature to
enhance display readability in low light conditions. It
can be easily toggled on and off through the keypad by
pressing Light.
Note: The backlight automatically shuts off after a set time period to
save battery life (see SETUP for details, page 21).
If battery percentage is less than 20% the backlight can not be ON.

H CALIBRATIONH CALIBRATION
Hanna recommends frequent calibrations, especially if high accuracy is
required.
The pH range should be recalibrated:
• Whenever the pH electrode is replaced.
• At least once a week, but daily is recommended.
• After testing aggressive chemicals.
• After electrode is cleaned.
• When calibration alarm time out is expired - “Cal Due” tag blinks (if
feature is enabled).
• If “Outside Cal Range” message blinks during pH measurement
(the measurement range is not covered by current calibration).
PROCEDURE
The instrument offers a choice of 7 buffers that are automatically recognized
(1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45 pH) and also allows
the user to enter two more pH values for calibration, “Custom 1” and
“Custom 2”. The set custom buffers are the buffer values at 25 ºC.
HI 98160 offers also 3.00 pH buffer choice for wine measurement.
When a custom buffer is selected during calibration, the “Custom” tag
is displayed on the LCD and its value can be changed in a ±1.0 pH
window, around the set value, in accordance with current temperature.
For accurate pH measurements, it is recommended to perform a five-point
(HI 98150 & HI 98160) calibration respectevely a three-point (HI 98140)
calibration. However, at least a two-point calibration is suggested.
The instrument will automatically skip the buffers used during calibration
and the buffers which are in a ±0.2 pH window, around one of the
calibrated buffers.
• Pour small quantities of selected buffer solutions into clean beakers.
For accurate calibration use two beakers for each buffer solution, the
first one for rinsing the electrode and the second one for calibration.
• Remove the protective cap and rinse the electrode with some of the
buffer solution to be used for the first calibration point.
FIVE-POINT CALIBRATION (HI 98150 & HI 98160)
• Submerse the pH electrode and the temperature
probe approximately 3 cm (1¼”) into a buffer
solution of your choice (pH 1.68, 4.01, 6.86,
7.01, 9.18, 10.01, 12.45 or a custom
buffer) and stir gently. The temperature
probe should be close to the pH electrode.
• Press CAL. The instrument will display the
measured pH on the primary LCD and “7.01”
buffer on the secondary LCD, together with
“CAL” and “Cal Point 1” tags.

• The calibrated value is then displayed on the primary LCD and the
secondary LCD will display the third expected buffer value.
• After the second calibration point is confirmed, submerse the pH
electrode and the temperature probe approximately 3 cm (1¼”) into
the third buffer solution and stir gently. The temperature probe
should be close to the pH electrode.
• If necessary, press the ARROW keys to select a different buffer value.
• The “ ” tag will blink on the LCD until the reading is stable.
• When the reading is stable and close to the selected buffer, “CFM”
tag blinks.
• Press CFM to confirm calibration.
• The calibrated value is then displayed on the primary LCD and the
secondary LCD will display the fourth expected buffer value.
• After the third calibration point is confirmed, submerse the pH
electrode and the temperature probe approximately 3 cm (1¼”) into
the fourth buffer solution and stir gently. The temperature probe
should be close to the pH electrode.
• If necessary, press the ARROW keys to select a different buffer value.
• The “ ” tag will blink on the LCD until the reading is stable.
• When the reading is stable and close to the selected buffer, “CFM”
tag blinks.

• The calibrated value is then displayed on the primary LCD and the
secondary LCD will display the fifth expected buffer value.
• After the fourth calibration point is confirmed, submerse the pH
electrode and the temperature probe approximately 3 cm (1¼”) into
the fifth buffer solution and stir gently. The temperature probe
should be close to the pH electrode.
• If necessary, press the ARROW keys to select a different buffer value.
• The “ ” tag will blink on the LCD until the reading is stable.
• When the reading is stable and close to the selected buffer, “CFM”
tag blinks.
• Press CFM to confirm calibration.
• The instrument stores the calibration values and
returns to normal measurement mode.
Note: For HI 98140 calibration proceed as in the FIVE-POINT CALIBRATION
above. After the third point is confirmed the instrument stores the
calibration value and returns to measurement mode.
FOUR, THREE or TWO-POINT CALIBRATION
• Proceed as described in FIVE-POINT CALIBRATION section.
• Press CAL after the appropriate accepted calibration
point. The instruments will return to measurement
mode and will memorize the calibration data.
ONE-POINT CALIBRATION
Two SETUP selectable options are available for one-point calibration:
“Pnt” and “OFFS”. See page 22 for Setup information using “1Pnt”
parameter.
If the “Pnt” option is selected, the adjacent slopes will be recalculated
using the new calibration value.
If the “OFFS” option is selected, an electrode offset correction is performed
keeping the existing slopes unchanged, but offsetting all by same value.
• Proceed as described in FIVE-POINT CALIBRATION section.
• Press CAL after the first calibration point was confirmed. The
instruments will memorize the one-point calibration
data and will return to measurement mode.
Notes: • Press Range to toggle between pH buffer
and temperature reading during calibration.
• If the value measured by the instrument is not close to the
selected buffer, “WRONG” “ ” and “WRONG” “ ” tags
will blink alternately. In this case check if the correct buffer
has been selected or used, or regenerate the electrode by
following the Cleaning Procedure (see page 39). If necessary,
change the buffer or the electrode.
• If the buffer temperature or the manual temperature exceeds
the temperature limits of the buffer, “WRONG” “ ” tags
and temperature reading will blink.
13
• If “WRONG” tag and “OLd” message are displayed on
the secondary LCD, an inconsistency exists between new
and previous (old) calibration data. Clear old calibration
parameters and proceed with calibration from the current
calibration point. The instrument will keep all confirmed
values during current calibration.
• With one-point calibration there is no “Condition” and only
the frame is shown. Calibration time out is active.
• Each time a buffer is confirmed, the new calibration
parameters replace the old calibration parameters of
the corresponding buffer.
If current confirmed buffer has no
correspondence in the existing stored
calibration and this is not full, the
current buffer is added to the existing
stored calibration.
If the existing stored calibration is
full (five calibration points), after confirming the last
calibration point, the instrument will ask which buffer will be
replaced by current buffer.
Press the ARROW keys to select another buffer to be replaced.
Press CFM to confirm the buffer that will be replaced.
Press CAL to exit this function. In this case, the buffer
calibration will not be stored.
Note: The replaced buffer is not removed from the calibration list and
can be selected for the next calibration.
WORKING WITH CUSTOM BUFFERS
If a custom buffer was configured in SETUP menu, it can be selected for
calibration by pressing the ARROW keys. The “CUSTOM” tag will be
displayed blinking on the LCD.
Press 2nd then Setup if you want to adjust
the buffer value to it’s value at the current
temperature. The buffer value, displayed on
the secondary LCD, will start blinking.
Use the ARROW keys to change the buffer value.
After about 5 seconds, the last buffer change
will be updated. Press 2nd then Setup if you want to change it again.
Notes: • Custom buffer value can be adjusted in a ±1.00 pH window,
around the set value.
• If you want to return to the set custom buffer value, simply
press the ARROW keys ( then ) to select again the
custom buffer.
14
CLEAR CALIBRATION
To clear calibration press 2nd then CLR or CLR alone
after entering CAL mode. The “CLr ALL” message will
be displayed on the LCD along with “Cal Due” CLR
message blinking.
All old calibrations, starting with current selected buffer are cleared and
the instrument continues calibration.
Note: If CLR is pressed during the first calibration point, the instrument
returns to measurement mode.
CONDITION
The display is provided with a 5-dot bargraph (unless the feature is
disabled) which gives an indication of the electrode status after
calibration as follows:
Bargraph indication Condition value
All 5 dots steady 81 to 100% of life
4 dots steady 61 to 80%
3 dots steady 41 to 60%
2 dots steady 21 to 40%
1 dot steady 1 to 20%
1 dot blinking 0%
Only frame is ON No info available
The “condition” bargraph remains active until the end of the calibration day.
Note: The electrode condition is evaluated only if current calibration
includes at least two standard buffers.
CLEAN ELECTRODE
Each time pH calibration is performed, the instrument internally compares
the new calibration with the one previously stored.
When this comparison indicates a significant difference, the “CLEAN” “ ”
tags blink on the LCD to advise the user that the pH electrode may need
to be cleaned (see ELECTRODE CONDITIONING & MAINTENANCE section
for details, page 37).
After cleaning, perform a new calibration.
Note: If calibration data are cleared, the comparison is done with the
default values.

The temperature has an effect on pH. The calibration buffer solutions are
affected by temperature changes to a lesser degree than normal
solutions. During calibration the instrument will automatically calibrate
to the pH value corresponding to the measured or set temperature.
During calibration the instrument will display the pH buffer value at 25 ºC.

GLP is a set of functions that allows storage and retrieval of data
regarding the maintenance and status of the electrode.
All data regarding pH or Rel mV calibration is stored for the user to
review when necessary.
HI 98140 and HI 98150 use electrodes with built-in EEPROM in which
calibration data is read at start up and stored after calibration. The
meter can automatically analyze the data and advise the user during
measurements if a problem is found with a clear message.
If the calibration offset is outside ±30 mV window, “OLD Probe” tag is
displayed blinking to warn user to perform a cleaning procedure.
If the calibration offset is outside ±60 mV window “DEAD Probe” tag
is displayed blinking to warn the user that readings are not reliable.
EXPIRED CALIBRATION
The instrument is provided with a real time clock (RTC), to monitor the
time elapsed since the last pH calibration.
The real time clock is reset every time the instrument is calibrated and the
“expired calibration” status is triggered when the instrument detects a
calibration time out. The “Cal Due” tag will start blinking to warn the
user that the instrument should be recalibrated.
The calibration time out can be set (see SETUP for details, page 21) from
OFF (function disabled) to 7 days.
For example, if a 4 days time out has been selected, the instrument will
issue the alarm exactly 4 days after the last calibration.
However, if at any moment the expiration value is changed (e.g. to
5 days), then the alarm will be immediately recalculated and appear
5 days after the last calibration.
Notes: • When the instrument is not calibrated or calibration is cleared
(default values loaded) there is no “expired calibration”,
and the display always shows the “Cal Due” tag blinking.
• When an abnormal condition in the RTC is detected, the
instrument forces the “expired calibration” status.
LAST pH CALIBRATION DATA
The last pH calibration data is stored automatically
after a successful calibration.
To view the pH calibration data, press 2nd then
GLP when the instrument is in pH measurement
mode.
The instrument will display the date (mm.dd)
and the time (hh:mm) of the last calibration.
The “condition” bargraph remains active until the end of the calibration day.
18
Press the ARROW keys to view the next
calibration parameter (pressing the key):
• The pH calibration slope and offset.
The GLP slope is the average of the calibration slopes; the percentage is
referred to the ideal slope value. For example 59.16 mV/pH at 25 °C.
• The calibration buffers in calibrating order,
for the last calibration.
The first pH calibration buffer:
The second pH calibration buffer (if exist):
The third pH calibration buffer (if exist):
The fourth pH calibration buffer (if exist):
The fifth pH calibration buffer (if exist):
19
Notes: • The “OLd” message displayed beside the pH value means
that this buffer was not used during last calibration. Press
2nd then Setup if you want to see calibration date (or time,
if old calibration was performed in the same day with current
calibration). In this case, the calibration buffer number is not
displayed on the LCD.
• If “not CAL” message appears on the LCD, the instrument
informs you that calibration was performed in less than five
points.
• The Calibration Alarm Time Out status.
If disabled,
or the number of days until the calibration
alarm will be displayed (e.g. 5 days), or

The temperature limit for the HI 1230B and HI 1618D is from 0 to 80 °C
with optimum measurements between 20 and 40 °C. The resistance of
glass electrodes partially depends on the temperature. The lower the
temperature, the higher the resistance. It takes more time for the
reading to stabilize if the resistance is higher. In addition, the response
time will suffer to a greater degree at temperatures below 25 ºC (77 ºF).
Since the resistance of the pH electrode is in the range of 50 to 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.
The HI 1618D and HI 1230B are specified for a pH range of 0 to 13 pH.
Alkaline Error
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 called
alkaline error and causes the pH to be underestimated. Hanna’s glass
formulations have the indicated characteristics.

Not present in gel electrodes.
PREPARATION PROCEDURE
Remove the electrode protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is
normal with electrodes and they will disappear when rinsed with water.
Do not be concerned if salt crystals are visible inside the electrode. This will
not effect function.
During transport tiny bubbles of air may have formed 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 HI 70300
Storage Solution for at least one hour or longer.
37
MEASUREMENT
Verify if electrode is calibrated before making measurements. Rinse the
pH electrode tip with distilled water. Submerse the tip (bottom 3 cm /1¼”)
in the sample and stir gently for a few 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.
See if the ORP probes tip is completly submersed.
STORAGE PROCEDURE
To minimize clogging and assure a quick response time, the glass bulb and the
junction of pH electrode should be kept moist and not allowed to dry out.
Replace the solution in the protective cap with a few drops of HI 70300
or HI 80300 Storage Solution or, in its absence, with pH 4 buffer.
Follow the Preparation Procedure on page 37 before taking measurements.
Note: NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WATER.
PERIODIC MAINTENANCE
Inspect the electrode and the cable. The cable used for connection to the
instrument 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.
38
pH CLEANING PROCEDURE
• General Soak in Hanna HI 7061 or HI 8061 General
Cleaning Solution for approximately ½ hour.
• Protein Soak in Hanna HI 7073 or HI 8073 Protein
Cleaning Solution for 15 minutes.
• Inorganic Soak in Hanna HI 7074 Inorganic Cleaning
Solution for 15 minutes.
• Oil/grease Rinse with Hanna HI 7077 or HI 8077 Oil
and Fat Cleaning Solution.
IMPORTANT: After performing any of the cleaning procedures, rinse the
electrode thoroughly with distilled water and soak the electrode in
HI 70300 or HI 80300 Storage Solution for at least 1 hour before taking
measurements.
