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.

and insert batteries, observing the polarity (see “Battery
Replacement“).
TO CONNECT THE ELECTRODE
With the meter turned off, connect the HI12973 probe to the
DIN socket on the bottom of the meter by aligning the pins
and pushing in the plug firmly. Remove the protective cap
from the probe before taking any measurements.

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 mea‑
surement 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 third LCD.
- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the third LCD.
- Compatible pH probes: HI12963, HI10483,
HI12943. If one of these probes are detected
“NoORP“message is displayed at start-up and “---“
message displayed on the secondary LCD while in
measurement mode.
- If the readings are out of range, the nearest range limits
are displayed blinking (E.g. -2.00 pH -5.0 °C).
TO SELECT THE MEASUREMENT RANGE
While in measurement mode, press the SET button to select
pH or pH‑mV measurement on the first LCD line.

TO FREEZE THE MEASUREMENT VALUES
While in measurement mode, press and hold the SET button
until “HOLD“ appears on the third LCD. The “HOLD“
remains for 1 second and reading of pH, ORP and tem‑
perature will be frozen on the LCD with “H” blinking.
Press any button to resume active measurements.
TO ENTER CALIBRATION MODE
Press and hold the button until ”POWER” and tag
is replaced by “STD“ and tag. Release the button.
TO ENTER SETUP MODE
Press and hold button until “STD“ and tag is re‑
placed by “SETUP“ and tag. Release the button.
TO TURN THE METER OFF
Whileinmeasurementmode,pressthe button.”POWER”
and tag will appear. Release the button.
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 soaking 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.
