GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI 9810 is the most complete and versatile portable pH/EC/TDS
meters ever manufactured. Designed with utmost precision and
simplicity, this meter provides 3 kinds of measurements. The pH, EC
and TDS ranges are easily selected using a membrane keyboard on
the front panel.
The conductivity of a solution depends on the temperature and for this
reason measurements are carried out with reference to a standard
temperature of 25C. If the solution measured has a different temperature than 25C, compensation must be performed.
HI 9810 automatically compensates for temperature changes with a
built-in temperature sensor and circuitry. The temperature coefficient
is fixed at 2%/C.
HI 9810 is designed for simplicity of use in taking pH, µS/cm and
mg/L measurements.

INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Slide off the
battery compartment cover on the back of the meter (see page 16),
install the battery while paying attention to its polarity.
Connect the probe to the DIN socket on the
top of the meter by aligning the pins with
the socket and pushing in the plug.
Always remove the electrode protective cap before taking any measurements.
Make sure the meter has been calibrated before taking any measurements (see pages 8 and 9 for calibration
procedures).
Turn the meter on by pressing the ON/OFF key.
TAKING PH MEASUREMENTS
If the electrode has been left dry, soak the tip in a pH 7 or pH 4
buffer solution for a few minutes to reactivate it.
TAKING EC/TDS MEASUREMENTS
• Immerse the tip of the electrode (4cm/1½") into the
sample to be tested. If possible, use plastic beakers
or containers to minimize any EMC interference.
• Tap the electrode lightly on the bottom of the
beaker to remove any air bubbles which may be
trapped inside the tip.
• Select the appropriate measurement range (EC or TDS).
• Wait for 1-2 minutes for the temperature sensor to attain thermal
equilibrium. The display will then show the measurement automatically temperature compensated for temperature with the
appropriate indication among the following:
µS symbol indicates the meter is in
µS/cm, EC mode
- No symbol indicates the meter is in TDS
mode.
• To take a pH measurement simply submerge the tip
(4cm/1½") of the combination pH/EC/TDS electrode
into the sample to be tested.
• Select the pH mode .
• Shake the electrode briefly while submerged and allow a couple of minutes
for the electrode to adjust and stabilize.
The display will show the pH value.
• If measurements are taken in different samples successively, it is
recommended to rinse (clean) the electrode thoroughly to eliminate cross-contamination. After cleaning, it is recommended to
rinse the electrode with some of the sample to be measured.

Note: If the case of an erroneous reading, the "E" indication will
appear on the right of the display.
AFTER MEASUREMENTS
After measurements have been completed, the instrument should be
switched off and the probe cleaned and covered with the protective
cap.
