that the instrument functions correctly. All
defective items must be returned in the original packing together with the supplied accessories.
GENERAL DESCRIPTION
HI 991300 and HI 991301 have been designed to
offer you the combination of pH, electro-conductivity ,
total dissolved solids and temperature measurements.
To increase precision, two models are available,
with different conductivity ranges, for applications from
purified to brackish waters.
All operations and settings, including calibration buffers and temperature scale selections, are made
through only 2 buttons.
The housing is waterproof and rated for IP 67 conditions.
The supplied multi-parameter probe, HI 1288, includes pH, EC/TDS and temperature in one convenient, rugged handle. In addition, to ensure against
interference from transient electrical noise, a solidstate amplifier is integrated into the probe.
Other user selectable features include different TDS
factors from 0.45 to 1.00, and a range of temperature coefficients (β) from 0.0 to 2.4% for greater
consistency and reproducibility.

OPERATIONAL GUIDE
• Connect the HI1288 probe to the DIN socket
on the top of the meter by aligning the pins and
pushing in the plug. Tighten the nut to ensure a
good connection. Remove the protective cap from
the probe before taking any measurement.
• Press and hold the MODE button for 2 seconds. All
the used segments on the LCD will be visible for a
few seconds, followed by a percent indication of
the remaining battery life (e.g. % 100 BATT).
• Select the measurement range (pH, EC or
TDS) by pressing the SET/HOLD button while in
normal measurement mode. The meter will display the pH, EC or TDS value on the primary
LCD, while temperature will be simultaneously displayed on the bottom (e.g. pH 5.73 and 22.5 °C).
• To change the temperature unit (from °C to
°F), press and hold the MODE button until “TEMP”
and the current temperature unit are displayed on
the secondary LCD (e.g. TEMP °C). Then use
SET/HOLD to change the temperature unit, and
press the MODE button until the meter returns to
normal measurement mode.
• To freeze the display, press and hold SET/HOLD
until “HOLD” appears on the secondary display
(e.g. pH 5.73 hold). Press either button to return to
normal mode.
• To turn the meter off, press and hold the MODE
button while in normal measurement mode. “OFF”
will appear on the lower part of the display. Release the button.
pH MEASUREMENT & CALIBRA TION
• Before taking any measurement make sure the
meter has been calibrated.
• If the probe has been left dry, soak in a storage or
pH 7 solution at least for one hour to reactivate it.
• Select the pH mode with the SET/HOLD button.
• Submerge the probe in the sample to be tested
while stirring it gently. Wait until the stability indicator on the top left of the LCD disappears.
• The pH value automatically compensated for temperature is shown on the primary LCD, while the
secondary LCD shows the sample temperature.
• If measurements are taken in different samples successively , rinse the probe tip thoroughly with water and then with some of the next sample to be
measured.
Calibration Buffer Set Selection
• While in pH measurement mode, press and hold
the MODE button until “TEMP” and the current
temperature unit are displayed on the lower LCD
(e.g. TEMP °C).
• Press the MODE button again to show the current
buffer set: “pH 7.01 BUFF” (for 4.01/7.01/10.01)
or “pH 6.86 BUFF” (for 4.01/6.86/9.18).
• Press SET/HOLD to change the buffer set.
• Press MODE to return to normal pH mode.
pH Calibration
• While in pH measurement mode, press and hold
the MODE button until “CAL” is displayed on the
lower LCD.
• Release the button. The LCD will display “pH 7.01
USE” (or “pH 6.86 USE”, if you have selected the
NIST buffer set).
• For a single point pH calibration, place the
probe in any buffer from the selected buffer set
(eg. pH 4.01 or pH 7.01 or pH 10.01). The meter
will automatically recognize the buffer value.
If using pH 7.01 (or pH 6.86 from the NIST buffer
set), after recognition of the buffer press MODE to
return to the pH measurement mode.
• For a two point pH calibration, place the probe
in pH 7.01 (or pH 6.86, if you have selected the
NIST buffer set). The meter will recognize the buffer
value and then display “pH 4.01 USE”.
• Place the probe in the second buffer (pH 4.01 or
10.01, or, if using NIST, pH 4.01 or 9.18). When
the second buffer is recognized, the LCD will display “OK” for 1 second and the meter will return to
normal measurement mode.
To Clear Previous Calibrations, press the MODE
button after entering the calibration mode. The lower
LCD will display “ESC” for 1 second and the meter
will return to normal measurement mode. The “CAL”
tag on the LCD will disappear and the meter will be
reset to the default calibration.
EC/TDS MEASUREMENTS & CALIBRA TION
• Place the probe in the sample to be tested. Use
plastic beakers or containers to minimize any electromagnetic interference.
• Select either EC or TDS mode with the SET/HOLD
button.
• T ap 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 equilibirium (i.e. until the stability
indicator on the top left of the LCD disappears).
• The meter will show the EC or TDS value automatically compensated for temperature, and the
temperature of the sample.
Selection of the TDS Conversion Factor
(CONV) and T emperature Coefficient (BETA)
• While in EC or TDS measurement mode, press
and hold the MODE button until “TEMP” and the
current temperature unit are displayed on the lower
LCD (e.g. TEMP °C).
• Press the MODE button again to show the current
conversion factor (e.g. 0.50 CONV).
• Press the SET/HOLD button to change the value.
• Press the MODE button to show the current temperature compensation coefficient (e.g. 2.1 BETA).
• Press the SET/HOLD button to change the value.
• Press MODE to return to normal operation.
EC Calibration
• While in the EC measurement mode, press and
hold the MODE button until “CAL” is displayed on
the lower LCD.
• Release the button and immerse the probe in the
HI 7031 calibration solution (“µS 1413 USE”).
• Once the calibration has been automatically performed, the LCD will display “OK” for 1 second
and return to normal measurement mode.
• Since there is a known relationship between
the EC and TDS reading, it is not necessary
to calibrate the meter in TDS. If the TDS conversion factor is either 0.5 or 0.7, the meter
will allow a direct calibration in ppm by using the Hanna TDS calibration solutions (see
“Accessories” section).
BA TTERY REPLACEMENT
The meter displays the remaining battery percentage every time it is turned on. When the battery level
is below 5%, the low battery indicator on the bottom
left of the LCD lights up to warn the user. If the battery
level is low enough to cause erroneous reading, the
Battery Error Prevention System (BEPS) will automatically turn the meter off.
To change the batteries, remove the 4 screws located on the back of the meter and carefully replace
the four AAA batteries, while paying attention to their
polarity . Replace the back and tighten the screws,
while checking that the gasket is in place to ensure a
watertight seal.
