GENERAL DESCRIPTION and INTENDED USE
The HI991300 and HI991301 are light weight, portable
pH, conductivity (or total dissolved solids) and temperature
meters for portable applications requiring both a pH and
conductivity (or TDS) measurement. Applications include
measurements for greenhouses irrigation, hydroponics and
groundwater monitoring from agriculture nutrient pollution.
The HI991300 and HI991301 meters feature 2 button
operation and are simple to use. All operations and set‑
tings, including calibration buffers and temperature scale
selections, are made through these 2 buttons. They have
a waterproof and compact casing rated for IP67 conditions
and a large Tri‑line display. The meters have automatic pH
calibration at one or two points and a single conductivity
calibration. Other user selectable features include different
TDS factors from 0.45 to 1.00, and a range of temperature
coefficients (b) from 0.0 to 2.4% for better conductivity or
TDS solution temperature compensation. These meters are
supplied with a multi‑parameter probe specifically designed
for these meters. To increase conductivity accuracy, two me‑
ter models are available, with different conductivity ranges,
for applications from purified to brackish waters.
The HI12883 multi‑parameter probe, incorporates a
domed shaped pH bulb rated from 0‑13 pH, a single
junction Ag/AgCl reference electrode with gelled electro‑
lyte and a retractable cloth wick junction, a graphite EC/
TDS cell, and a temperature sensor in one convenient,
rugged polypropylene body. In addition, to ensure against
interference from transient electrical noise to pH, a solid‑
state preamplifier is integrated into the probe. The probe
is rated from 0 to 50°C.

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 clean‑
ing 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, the EC, TDS or pH‑
mV value on the secondary LCD, while the third LCD

11
line displays the sample temperature. If measurements are
taken in different samples successively, rinse the probe tip
thoroughly†to eliminate cross‑contamination. For better ac‑
curacy, 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
Select calibration type “STD“ .
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

12
Two-point calibration
Proceed with steps 1 through 3 under single point calibration
using 7.01 pH (pH 6.86 for NIST) 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.
pH ELECTRODE CONDITION
The display is provided with a probe icon (unless the feature
is disabled from setup) which indicates the pH 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 pH
calibration has two points.
OPERATIONAL GUIDE

13
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 pH 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 before measuring
the offset and then hydrated in storage solution for a
minimum of 30 minutes before calibrating the probe.
EC MEASUREMENT AND CALIBRATION
Place the probe in the sample to be tested. Use plastic
beakers or containers to minimize any electromagnetic
interference. Tap the probe lightly on the bottom of the
container to remove air bubbles that may be trapped inside
the tip. Wait for a few minutes for the temperature sensor
to reach thermal equilibrium, when the tag disappears.
The LCD displays the EC or TDS value (automatically
compensated for temperature) on the secondary LCD, while
the third line LCD displays the sample temperature.
OPERATIONAL GUIDE

14
EC calibration
Before calibration, rinse the sensor tip with a heavy stream
of purified water then shake excess water from the probe.
Select calibration type “EC STD“ . The meter enters the
calibration mode and “μS 1.41 USE” (HI991300) or “mS
12.88 USE“ (HI991301) is displayed with tag blinking.
Immerse the probe in calibration solution. If the standard value
is recognized “REC“ is displayed then “WAIT“ until the
calibration is accepted. The LCD will display “SAVE” for
1 second and return to normal measurement mode. If the
standard is not recognized or the slope is out of accepted range
“--- WRONG“ is display. Change the calibration solution,
clean the electrode or press any key to exit calibration. When
the calibration procedure is completed, the tag is turned on.
Note: - Beta should be set to 1.9 during calibration.
- Since there is a known relationship between the EC and
TDS reading, it is not necessary to calibrate the meter in
TDS. If the conversion factor is either 0.5 or 0.7, the meter
will allow a direct calibration in TDS by using the Hanna
calibration solutions.
SETUP MODE
Setup mode allows the selection of the Temperature
unit, Auto‑off, Beep, the type of pH buffer set, the
pH Resolution, enable/disable calibration Information
display, temperature compensation factor for EC and
TDS conversion factor. To enter Setup mode press and
hold button until “EC STD“ and tag is replaced
by “SETUP“ and tag. Release the button.
• “TEMP“ is displayed on the third
LCD line with the current temperature
unit (E.g. “TEMP °C“), for °C/°F
