GENERAL DESCRIPTION and INTENDED USE
The HI991003 is a light weight, portable pH/ORP/
temperature meter for pH and ORP measurements
encountered in recreational waters (swimming pools and
spas), plating baths, water treatment, manufacturing
and environmental testing applications. The HI991003
meter features 2 button operation and is simple to use.
The HI991003 has a waterproof and compact casing,
large Tri‑line display, and automatic pH calibration at
one or two points. The meter is supplied with a rugged
probe protected with a titanium body specially designed
for use on this meter.
The HI12973 pH/ORP probe has a built‑in temperature
sensor for simultaneous temperature compensated pH
and temperature readings, and contains a preamplifier to
provide stable measurements in electrically noisy environ‑
ments. The probe contain a pH sensor with cylindrically
shaped bulb. The probe also contains a single junction
gel filled Ag/AgCl reference electrode with a cloth junction.
Should the junction become fouled, simply pull out the
cloth and trim off the fouled portion. The ORP sensor is
platinum and utilizes the same reference electrode as
the pH electrode. Voltages displayed from this sensor
are referenced to the Ag/AgCl reference with 3.5M KCl
activity.

OPERATIONAL GUIDE
The LCD displays the pH value (automatically compensated
for temperature) on the primary LCD, the ORP value on
the secondary LCD, while the third LCD line displays the
sample temperature. If measurements are taken in different
samples successively, rinse the probe tip thoroughly†to elimi‑
nate cross‑contamination. For better accuracy, frequent cal‑
ibration 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.

OPERATIONAL GUIDE
Two-point calibration
Proceed with steps 1 through 3 under single point calibra‑
tion 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 calibra‑
tion 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.
ELECTRODE CONDITION
The display is provided with a probe icon (unless the fea‑
ture 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.
Impex Produkter

OPERATIONAL GUIDE
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.
ORP MEASUREMENT
Make sure the probe is connected. Place the probe into
the sample to be tested, stir briefly and wait until the
tag on the LCD is turned off. The meter will show the ORP
(mV) value on the secondary LCD together with the pH of
the solution (first LCD line) and the temperature of the
sample (third LCD line).
Notes: ‑The ORP range is factory calibrated and cannot
be calibrated by the user. HI7020L ORP solution can
be used to validate ORP sensor is reading correctly.
‑“ATC“ tag turns off because the mV readings are
not temperature compensated.
