GENERAL DESCRIPTION and INTENDED USE
HI99192 is a portable, lightweight pH meter with two
button operation that is simple to use. Features include a
waterproof and compact casing, large dual‑line display,
low battery detection, automatic pH calibration at one or
two points and selectable temperature unit (°C or °F). The
HI99192 meter comes with a FC2153 pH which is, de‑
signed specifically for measuring the pH of potable waters.
The pair are ideal for on‑site spot checks of drinking water.
The pH of potable water is fundamental to ensure safe water
quality. If the pH is too low, drinking water will be corrosive
to the distribution system and water pipes in homes. If it is
too high, it can reduce the effectiveness of disinfectants. The
pH of water also influences aesthetic or cosmetic properties
including taste, odor, and, clarity. Most public water opera‑
tions maintain pH between 6.5 and 8.5.
Many factors affect pH measurements. An accurate tem‑
perature measurement and temperature compensated pH,
along with at least two calibrated pH standards will improve
the quality of the pH measurement. Often pH electrodes
respond sluggishly in potable water samples due to the na‑
ture of the water, the sample temperature or the design of
the electrode.
The HI99192 together with the FC2153 pH electrode solves
all the problems found with standard pH systems. This spe‑
cialized electrode offers numerous features that improve pH
testing in drinking water. The spherical pH bulb features a
low resistance pH glass that responds quickly to the sample
(even at cold temperatures). It also has a refillable single
junction Ag/AgCl reference that is used with a KCl electrolyte
and has three ceramic junctions to ensure continuity and
provide quick and reproducible measurements (even in low
ionic strength waters).
FC2153 pH electrode has a built‑in temperature sensor for
temperature compensated pH and temperature readings
and contains an integral preamplifier to provide stable
measurements in electrically noisy environments.

OPERATIONAL GUIDE
TO TURN THE METER ON
To turn the meter ON, press the button
on the front of the meter. If it does not turn
on, make sure that the batteries are properly installed
in their place. The meter is provided with an active
acoustic signal when a key is pressed. At start‑up the
meter displays all LCD segments for a few seconds,
followed by the percentage indication of the remaining
battery life, displaying “WAIT“ until electrode check is in
process then the meter enters the normal measurement mode.
Note: The meter detects the presence and the type of the
probe at its input.
- If the probe is not connected the message “NO”
”PROBE“ appears alternatively on the secondary LCD
with “---“ blinking on the first LCD line.
- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the secondary LCD
with “---“ blinking on the first LCD line.
- If the readings are out of range, the nearest range
limits are displayed blinking (E.g. -2.00 pH -5.0 °C).

pH MEASUREMENT & CALIBRATION
Make sure the meter has been
calibrated before use.
If the probe is dry, soak it in
HI70300 storage solution for
30 minutes to reactivate it. If
fouled, clean the electrode by soak‑
ing in cleaning solution for 20 minutes, then rinse the tip
and soak in storage solution at least 30 minutes before use.
Rinse the electrode off well and shake off excess
droplets. Recalibrate before using. Submerge the probe in
the sample to be tested while stirring it gently. Wait until
the tag on the LCD disappears.
The LCD displays the pH value (automatically compensated
for temperature) on the primary LCD, while the second‑
ary LCD displays the sample temperature. If measurements
are taken in different samples successively, rinse the probe
tip thoroughly†to eliminate cross‑contamination.

11
OPERATIONAL GUIDE
For better accuracy, frequent calibration of the pH sensor
with the meter is recommended. In addition, the meter
must be recalibrated whenever:
a) The pH electrode is replaced.
b) After testing aggressive chemicals.
c) Where high accuracy is required.
d) At least once a month.
e) After cleaning the sensor.
†The probe tip should be rinsed with purified water (reverse osmosis,
distilled, or deionized) before and after placing in any solution (buffer,
storage, or sample).
pH calibration
Enter calibration mode while in
pH measurement mode. Place the
sensor into the first calibration
buffer. If performing a two‑point
calibration, use pH 7.01 (pH 6.86
for NIST) buffer first. The meter will
enter the calibration mode, displaying “pH 7.01 USE”
and tag blinking (or “pH 6.86 USE” for NIST).
Follow directions for single and two‑point calibration below:
Single-point calibration
1. Place the probe in any buffer from the selected buffer set.
The meter will automatically recognize the buffer value.
2. If the buffer is not recognized or the calibration offset is out
of the accepted range “---- WRONG“ is displayed.
3. If the buffer is recognized “REC“ is displayed then
“WAIT“ until the calibration is accepted.
If using pH 7.01 (or pH 6.86 for NIST), after acceptance
of the buffer press any key to exit. The ”SAVE” message is
displayed and the meter returns to pH measurement mode.
If using pH 4.01 or 10.01 (or pH 9.18 for NIST) buffer
the ”SAVE” message is displayed and meter returns to pH
measurement mode.

12
Two-point calibration
Proceed with steps 1 through 3 under single point
calibration using 7.01 (pH 6.86 for NIST) pH buffer
first. Then follow steps below:
The ”pH 4.01 USE” message is then displayed.
Place the probe in the second calibration buffer (pH 4.01
or 10.01, or, if using NIST, pH 4.01 or 9.18). When the
second buffer is accepted, the LCD will display “SAVE”
for 1 second and the meter will return to the normal
measurement mode.
If the buffer is not recognized or the slope is out of accepted
range ”--- WRONG” is displayed. Change the buffer, clean
the electrode or press any key to exit calibration.
It is always recommended to carry out a two‑point
calibration for better accuracy.
When the calibration procedure is completed, the tag
is turned on together with the calibrated points.
To exit calibration and reset default values
After entering the calibration mode and before the first point
is accepted, it is possible to quit the procedure and return
to the last calibration data by pressing the button. The
LCD displays “ESC“ for 1 second and the meter returns to
normal mode.
To reset the default values and clear a previous
calibration, press the SET button after entering the calibration
mode and before the first point is accepted.
The LCD displays “CLEAR“ for 1 second, the meter resets to
the default calibration and the tag with the calibrated
points on the LCD disappears.

13
ELECTRODE CONDITION
The display is provided with a probe icon (unless the feature
is disabled from setup) which indicates the electrode status
after calibration. The “condition” remains active for 12 hours
(unless the batteries are removed).
The electrode condition is evaluated only if the current
calibration has two points.
5 bars: excellent condition
4 bars: very good condition
3 bars: good condition
2 bars: fair condition
1 bar: poor condition
1 bar blinking: very poor condition
With 1 bar it is recommended to clean the electrode and
recalibrate. If there is still only 1 bar or 1 bar blinking
replace the probe.
Sensor Check
Setting the meter to pH‑mV range the user can check the
sensor status at any time. The offset value is the reading
in pH 7.01 buffer (@ 25 °C/77 °F). If this reading is
outside the range ±30 mV, the electrode is considered
“very poor”. The slope value of the sensor is the difference
between readings in pH 7.01 and in pH 4.01 buffers. When
the slope reaches the value of about 150 mV, the electrode
is considered “very poor“. When “poor“ or “very poor“, it
is recommended to replace it with a new one.
Note: To ensure reliable readings, the electrode must
be cleaned with cleaning solution and then hydrated in
storage solution for a minimum of 30 minutes before
calibrating the probe.
