GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI9017, HI9218, HI9219 and HI9318 are microprocessor-based benchtop meters designed to meet the most stringent demands of the laboratory.
They feature:
•user friendly rubber keyboard
•automatic calibration with memorized buffers values
•automatic or manual temperature compensation
•storage of calibration data even after the meters are shut off
•error codes to guide the user in calibration and troubleshooting
All these models incorporate a standard RS232C output for communication with a computer.
The HI76405 electrode holder provided will hold your pH electrode
and temperature probe directly over the sample vessel which can be
placed on the enamel coated base of the holder. A magnetic stirrer
can also be placed on the enamel coated base if sample agitation is
required. The enamel coating is impervious to most chemicals and the
heavy steel base will not tip over easily.
These meters are perfect for use in Q.C. labs, R&D labs, environmental testing, industrial processing, chemical treatment, waste water
treatment, drinking water analysis, titration, hydroponics, general agriculture, food processing and anywhere accurate pH measurements
are required.
• HI9017 pH/mV/°C meter automatically recognizes three stan-
dard calibration buffer values (pH 4.01, 7.01, 10.01). The pH
and temperature values are shown separately on the LCDs. A wide
mV range and high resolution allow for ORP or ion-selective
measurements (the range automatically switches from ISE to ORP
when readings exceed ±399.9 mV).
HI9017 comes supplied with HI1131B glass-body combination
pH electrode (with 1m/3.3' cable), HI7669/2W temperature probe
3
(with 1m/3.3' cable), 12VDC adapter (HI710005 or HI710006),
pH 4.01 & pH 7.01 buffer solutions (20 mL each), HI7071
electrolyte solution (30 mL), HI76405 electrode holder and a
dust cover.
• HI9218 and HI9219 are programmable pH/°C meter with built-
in printer. They print pH values together with temperature, time
and date. These meter provide you with pH and temperature
readings simultaneously and separately on the LCDs and feature a
unique stability indicator. When the pH electrode stabilizes in the
sample, the "NO" on the LCD changes to "YES". This indicates that
the reading is correct and can be recorded. They automatically
recognize three standard buffers (4.01, 7.01 and 10.01 pH) for
calibration purposes. These meters are extremely user-friendly,
giving step-by-step instructions on the printer at every stage to
help the user.
HI9218 has been specifically designed for the food industry.
HI9218 comes supplied with FC100B plastic-body combination
pH electrode (with 1m/3.3' cable) while HI9219 comes with
HI1131B glass-body combination pH electrode (with 1m/3.3'
cable). HI9218 and HI9219 are also supplied with: HI7669/2W
temperature probe (with 1m/3.3' cable), 12VDC adapter (HI710005
or HI710006), pH 4.01 & pH 7.01 buffer solutions (20 mL each),
HI7071 electrolyte solution (30 mL), 5 replacement rolls of printer
paper, HI76405 electrode holder and a dust cover.
• HI9318 is a pH/mV/°C meter designed for logging data in various
applications. This programmable printing meter prints pH or mV
values as well as sample number, temperature, time and date.
The pH/mV and temperature values are displayed on separate
LCDs for ease of reading. It recognizes and memorizes three
different standard buffers (pH 4.01, 7.01 and 10.01) for calibration purposes. The printer can be programmed to print in one of 6
different languages (English, French, German, Italian, Spanish or
Swedish). Once your language is selected you can simply prompt
the meter to calibrate and it will print step-by-step instructions
through the entire process making this meter perfect for use by
even non-technical staff members.
HI9318 comes supplied with HI1131B glass-body combination
pH electrode (with 1m/3.3' cable), HI7669/2W temperature probe
(with 1m/3.3' cable), 12VDC adapter (HI710005 or HI710006),
pH 4.01 & pH 7.01 buffer solutions (20 mL each), HI7071
electrolyte solution (30 mL), 5 replacement rolls of printer paper,

Electrode and probe connections
For combination pH (or ORP for HI9017 and HI9318) electrodes
(with internal reference) plug the electrode's BNC to the socket provided (#1).
For electrode with separate reference (see page 58), connect the
measuring electrode's BNC to the BNC socket (#1) and the reference
electrode's jack to the socket provided (#2 or #3).
For temperature measurements and automatic temperature compensation connect the temperature probe to the °C socket (#4).
RESET button
The RESET button (#5) is used when the instrument displays erroneous messages due to strong electrical interference or when the
instrument's power supply was disconnected before the meter was
switched off. Press the RESET button and restart the entire operation.

Power connection
Plug the 12VDC adapter (HI710005 or HI710006) into the DC socket
(#7).
Plug the adapter into the mains.
Note: The instrument uses the following configuration.
+
It is recommendable to use the Hanna HI7710005 or HI710006
voltage adapters (supplied witht the meters) that use the proper
polarity configuration.
The meters 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.
Note: Make sure the main line is protected by a fuse.
Note: HI9017, HI9218, HI9219, HI9318 use a rechargeable battery
to retain the pH calibration data only. It lasts approximately one
month when fully charged. The battery is automatically charged
any time the meter is plugged-in (either turned on or off).
Notes:
1)If you need to unplug the instrument, press the OFF key before
disconnecting the meter from the mains. Only in this case will
the instrument retain the memorized data. Otherwise, the instrument needs to be re-calibrated. In the case of a power
failure while the instrument is operational , re-calibration is
required.
2)When the instrument is initially switched on, the microprocessor
checks if any calibration data is in memory (i.e. if the offset is
within ±1 pH and the slope between 70 - 105%). If the
calibration data are not memorized, the offset and slope of the
instrument will be set to 0 mV and 100% respectively.

Make sure that the instrument has been calibrated for pH before
taking pH measurements (see page 18).
Connect the pH electrode (combination-type) or the electrode half cells
to the appropriate connectors on the rear panel (see page 11).
If automatic temperature compensation is required, connect the
HI7669/2W temperature probe to the proper socket on the rear panel
(see page 11).
Press the ON key to turn the meter on. The meter will
automatically default to the pH measurement mode.
Immerse the electrode and the temperature probe
in the sample and shake briefly. Wait for 30
seconds before taking readings.

The LCD on the right shows the pH reading compensated for temperature. The temperature reading is displayed on the LCD on the left.
Note: the electrode should be submerged approxi-
mately 4cm (1½") into the solution.
If the temperature probe is used, it should be
located as close to the pH electrode as possible.
If measurements are taken in different samples successively, it is
recommended that the electrode is rinsed thoroughly for better conditioning and to eliminate cross-contamination of the sample.

TAKING ORP MEASUREMENTS
(FOR HI 9017 AND HI 9318 ONLY)
HI9017 and HI9318 have the capability to take ORP measurements,
using an ORP electrode. Hanna Instruments offers a variety of ORP
electrodes for this purpose (see page 59). Contact your Dealer for more
information.
Just as pH measurements allow the acidity or the alkalinity of a
substance to be expressed in numbers, oxidationreduction potential (redox) measurements provide
the quantification of the oxidizing or reducing power
of any liquid.
Connect the ORP electrode to the meter and submerge the tip (4 cm / 1½") into the sample to be tested.
Note: ORP measurements are taken without temperature compensa-
tion.
Press the RANGE key once to enter the mV mode.
Allow a few minutes for the reading to stabilize.
The display will indicate the absolute mV value
(positive or negative).
When values are less than ±400 mV, tenths of
mV
mV are displayed; for values greater than ±400
mV, the decimal digit disappears.
Note that the change in scale (from 0.1 mV to 1 mV as resolution) is
automatic.

Procedure
• Turn the instrument ON after connecting the pH
electrode and the temperature probe.
• Immerse the temperature probe together with
the electrode into pH 7.01 buffer solution or
manually set the temperature to the temperature of the buffer (if you are not using the
temperature probe HI7669/2W see page 25).
Note: the electrode should be submerged approximately 4 cm (1½")
into the solution. The temperature probe should be positioned
as close to the pH electrode as possible.

PROGRAM #3 (HI9318)
This program prints the date, time, the offset and slope characteristics
of the pH electrode.
Note: the offset and the slope characteristics of the electrode are
referred to the last performed pH calibration.
No programming is required.
Simply press the 3 key and the PGM
key.
Changes in an electrode's performance
can be determined from this information.
If the electrode's offset is within 0.50 pH and 1.00 pH or -0.50 pH
and -1.00 pH, it indicates contamination. If the value exceeds ±1
pH the electrode should be
replaced.
The slope characteristic is in
percentage of the theoretical value of 58.16 mV per
pH unit at 20°C.

Data transmission from the instrument to
the PC is now much easier with the new
HI92000 Windows® compatible applica-
tion software offered by Hanna Instruments.
User friendly, HI92000 offers a variety of
features and has an on line help feature to
support you throughout all situations.
To install HI92000 you need a 3.5" drive and few minutes to follow
the instructions conveniently printed on the disk’s label.
Contact your Hanna Dealer to request a copy.
To connect your Hanna Instruments bench meter to the PC use
HI920010, available through your Hanna Dealer. Make sure that your
meter is switched off and plug the connectors, one into the meter
RS232C connector, the other into the serial port of your PC.
Note: Cables different from the HI920010 may use a different con-
figuration. In such case any communication between the meter
and the PC is not possible.
SETTING THE BAUD RATE
The transmission speed (baud rate) of the meter and the external
device must be identical. The meter is factory set to 1200.
If you wish to change this value, please contact your nearest Hanna
Center.
SENDING COMMANDS FROM PC
With terminal programs such as, for example, Telix®, Windows Terminal®, it is possible to remotely control your Hanna Instruments bench
meter. Use HI920010 cable to connect the meter to the PC, start the
terminal program and set the communication options as follows: 8, N,
1, no flow control.
COMMAND TYPES
To send a command to the pH meter the scheme is:
<DLE> <command> <CR>
This line makes the computer send a Data Link Escape character (the
command expressed as a number or a 3-character sequence) and a CR
character.
Note: Windows Terminal® and all the other terminal programs that
support the ANSI escape sequence, represent the DLE character
by the string ‘^P’ and the CR character by the string ‘^M’.
E.g. the line ‘^PPHR^M’ sets the range to pH.
TYPE OF COMMANDS
Commands not requiring an answer from the pH meter.
PHR sets the range to pH
MVR sets the range to mV
Commands requiring an answer:
PH? Causes the pH meter to send the pH value through the serial
interface. If the reading is out of range ("Err1"), "Err1" is sent
instead of the pH value.
If the range is set to mV (no pH reading available), "Err6" is
sent (for HI9218 and HI9219 only).
MV? Causes the pH meter to send the mV value through the serial
interface. If the reading is out of range ("Err2"), "Err2" is sent;
if the range is set to pH, "Err6" is sent.
TM? Causes the pH meter to send the temperature value. If this is
out of range, an "Err3" signal is sent instead.
For HI9218,
HI9219 and
HM? This orders the pH meter to send the time value (in hours and
minutes), A 5-character string is sent in HH.MM format.
MD? This orders the pH meter to send the data value (in months and
days). A 5 character string is sent in MM.DD format.
These commands may be sent with either capital or small letters. The
characters sent by the meter are always capital letters.
For HI9318 only:
a) Numerical data: a command line containing figures , the minus
sign and the decimal point will be interpreted by the pH meter as
if that number was sent by means of the keyboard. The maximum
number of figures allowed is 4.
b) Commands which do not require a response by the pH meter:
CAL is equivalent to pressing the CAL key
CON is equivalent to pressing the CON key
AKY is equivalent to pressing the A key
HI9318 only:
Windows Terminal ® is registered Trademark of "Microsoft Co."
47
BKY is equivalent to the B key
CKY is equivalent to pressing the C key
PGM is equivalent to pressing the PGM key
TEM is equivalent to pressing the TEMP key
PRT is equivalent to pressing the PRINT key
CLR is equivalent to pressing the CLEAR key
PHR brings the instrument into pH measurement range
MVR brings the instrument into the mV measurement range
PAP causes the paper to advance by one tenth of a line. In order to
advance the paper by one entire line, send a RETURN charac-
ter.
TIM causes the time to be shown on the date/time display
DAT causes the date to be shown on the date/time display
CHP sets the printer in the character printout mode
PPR sets the printer in the graph printout mode
KBS after this command, the keys pressed on the pH keyboard are
no longer recognized by the pH meter itself, but instead pro-
voke the transmission of a string to the host computer. Only the
OFF and the PAPER keys retain their proper functions. In this
way, the keyboard may also function as an input device to the
host computer, as well as command the pH meter.
Naturally the pH meter continues to obey the commands which
are equivalent to the keys pressed and sent by means of serial
interface.
KBU cancels the KBS command
The 4 commands IDL, SEP, SEV and RV? are reserved for future use
and are not described here.
INTERFACE WITH PC
If you are not using Hanna Instruments HI92000 application software, please find here below some additional information to help your
connection to the PC.
HOW TO CHANGE THE COMMAND PREFIX CHARACTERS
(FOR HI9017 & HI9318 ONLY)
It is sometimes necessary to change the character used to indicate that
a command is to follow.
If the computer connection already makes use of DLE of other functions, its use as a prefix for "c"-type commands may cause problems to
the operating system.
In order to change the prefix character run program #6 for HI9017,
by pressing the 6 key and then the PGM key or run program #9 for
48
HI9318 by pressing the 9 key and then the PGM key.
Enter the ASCII Code of the desired prefix character and then press the
ENTER A key for HI9017 or the A key for HI9318.
It is advisable to use a control character as a prefix (not RETURN,
which already performs other functions) or a non-control character
which is not being used for other purposes, for example the "@" sign
(ASCII Code64).
MORE ABOUT KBS COMMAND (FOR HI9318 ONLY)
The KBS Command (KeyBoard Send) disconnects the keyboard from
the pH meter and connects it to the RS 232C interface.
Whenever a key is pressed on the keyboard, a string of characters
which represents the key itself is sent by means of interface, followed
by a RETURN character.
The strings corresponding to the various keys are the following:
- the figures from 0 to 9 for the numbered keys;
- the minus sign (-) for the +/- key;
- the full stop (.) for the decimal point.
The other keys (CAL, CON, A, B, C, DATE, RANGE, PGM, TEMP, PRINT
and CLEAR) are represented by their own abbreviations.
The OFF and PAPER keys maintain their own functions and are not
sent to the computer.
GRAPHIC PRINTOUT (FOR HI9318 ONLY)
The HI 9318 printer may also be programmed for graphic mode
printing for the reproduction of bit graphs and maps: every 16 bytes of
data received from the pH meter produce an elementary line of dots
rather than a line of text.
In order to print one or more lines of dots (96 dots per line), the
computer must first send the PPR command to set the printer in the
graphic mode, then:
- divide the 96-dot line into 16 segments of 6 dots long,
- interpret each segment as a binary number (the left most dot will
be the most significant bit),
- add hexadecimal 20 or decimal 32 to each binary number and
- send the 16 numbers as 16 characters.

PREPARATION
Remove the 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.
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 HI70300 orHI80300 Storage Solution for at least one hour.
50
For refillable electrodes:
If the filling solution (electrolyte) is more 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 ElectrolyteSolution 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 at least
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 assuring a quick response time, the glass
bulb and the junction should be kept moist and not allowed to dry out.
Replace the solution in the protective cap with a few drops of HI70300or 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 the reference chamber 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.
51
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 Soak in Hanna HI7073 or HI8073 Protein Cleaning So-lution for 15 minutes.
- InorganicSoak in Hanna HI7074 or HI8074 InorganicCleaning Solution for 15 minutes.
- Oil/greaseRinse with Hanna HI7077 or HI8077 Oil and
Fat Cleaning Solution.
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 measurements.
TROUBLESHOOTING
Evaluate your electrode performance based on the following.
• 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 elec-
trodes only): refill with fresh HI7071 or HI8071 for single junction
or HI7082 or HI8082 for double junction electrodes.
• Dry Membrane/Junction: Soak in Storage Solution HI70300
or HI80300 for at least 1 hour.
• Drifting: Soak the electrode tip in warm Hanna Solution HI7082
or HI8082 for one hour and rinse tip with distilled water. Refillwith 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 Hanna Solution
HI7061 or HI8061 for 30 minutes, rinse thoroughly in distilled
water and then follow the Cleaning Procedure above.
The resistance of glass electrodes partially depends on the temperature.
The lower the temperature, the higher the resistance. It takes longer 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 10°C.

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 andstatic discharges are detrimental for 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 Temperature1- 3 years
90 °CLess than 4 months
120°CLess 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.
