Remove the instrument from the packing material and examine
it carefully. If any damage has occurred during shipment, please
contact your local Hanna Instruments Office.
The meters are supplied with:
• HI7630 conductivity probe
• calibration solution sachet, 20 mL:
HI70031 (1413 µS/cm) for HI993301
HI70030 (12.88 mS/cm) for HI993302

item must be returned in its original packing.
GENERAL DESCRIPTION
www.hannainst.com
The waterproof EC/TDS indicators HI993301 and HI993302
have been designed to meet the grower’s need for equipment
suited to the aggressive environments of agricultural and
hydroponics applications.
The instruments feature a large, dual-level, backlit LCD to give
instantaneous readings of both EC/TDS and temperature even
from a distance.
Calibration and temperature compensation are automatic, while
the TDS factor and temperature coefficient are user adjustable
for application specific measurements.
The HI7630 probe is provided with built-in temperature sensor,
and has been molded with pipe thread (1/2’’ NPT) for an easy
in-line installation.
Choose the indicator according to the proper EC/TDS ranges
for your application:
• HI993301 measures EC from 0 to 3999 µS/cm and TDS
from 0 to 2000 ppm
• HI993302 measures EC from 0.00 to 20.00 mS/cm and
TDS from 0.00 to 10.00 ppt

OPERATIONAL GUIDE
Preliminary operations
Connect the 12 Vdc adapter to the meter and to the mains;
the display will lit. Press and hold the MODE button for 2-3
seconds. All the used segments on the LCD will be visible for
a few seconds.
To change the temperature unit
To change the temperature unit (from °C to °F), from 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).
Use the SET/HOLD button to change the temperature unit, and
then press MODE button twice to return to normal measurement
mode.
To freeze the display
Press and hold the SET/HOLD button for 2-3 seconds until
“HOLD” appears on the secondary display.
Press either button to return to normal mode.
Taking measurements
Select either EC or TDS mode with the SET/HOLD button.
Immerse the probe in the solution to be
tested. For better accuracy, the probe
should not touch or stand close to the
walls or bottom of the sample vessel.
The EC or TDS value automatically
compensated for temperature variations,
is shown on the primary LCD, while the
secondary LCD shows the temperature
of the sample.
Measurements should be taken when the stability symbol on
the top left of the LCD disappears.
To change the TDS factor (CONV) and the temperature
compensation coefficient β (BETA)
• From 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).
• Use the SET/HOLD button to change the conversion factor.
• Press the MODE button to show the current temperature
compensation coefficient β (E.g. 2.1 BETA).
• Use the SET/HOLD button to change the value.
• Press MODE to return to normal measuring mode.
To turn the meter off
Press the MODE button while in normal measurement mode.
“OFF” will appear on the lower part of the display. Release the
button. The display still lit, until the power supply is connected.
Notes:
• Before taking any measurement make sure the meter has
been calibrated.
• To clear a previous calibration, 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 symbol on the LCD will disappear.
The meter will be reset to the default calibration.
• If measurements are taken in different samples successively,
rinse the probe thoroughly with water and then with some
of the sample to be measured.

(*) To be replaced by authorized technical personnel only.
• From 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 proper
calibration solution: HI70031 (1413 µS/cm) for HI993301
and HI70030 (12.88 mS/cm) for HI993302.
• Once the calibration has been automatically performed, the
LCD will display OK for 1 second and the meter will return
to normal measurement mode.
• Since there is a known relationship between EC and TDS
readings, it is not necessary to calibrate the meter in TDS
Note: for storing calibration data in the non-volatile
memory, turn the meter OFF and then ON again through
the MODE button.
The CAL symbol on the LCD means that the meter is calibrated.
