GENERAL DESCRIPTION
HI 8633 and HI 8733 have been designed specifically for use in the areas
of production and quality control. It is often necessary to test samples with
different concentrations ranging from deionized water to brine.
Both models can be manually calibrated at 1 point.
The HI 8733, with a built-in temperature sensor and Automatic
Temperature Compensation, is the perfect instrument for measuring
samples with fluctuating temperature.
HI 8734 has been specially designed for the water conditioning industry,
particularly in the softening, demineralization, reverse osmosis and
drinking water applications.
Three ranges of measurement assure the highest accuracy possible. In
addition, Manual Temperature Compensation is possible through a knob
on the front panel.
The ratio between conductivity and TDS is factory set at 0.5.
Moreover, the 4-ring potentiometric probes supplied with the meters are
made of rugged PVC - ideal for indoor, as well as outdoor measurements.

OPERATIONAL GUIDE
• Each meter is supplied complete with a 9V battery. Remove 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 meter securely
by aligning the pins with the socket
and pushing the plug in.
• Make sure that the meter has been calibrated before taking any
measurements (see "Calibration" section).
• Immerse the conductivity probe into the
sample, with the holes on the shaft
completely submerged.
If possible, use plastic beakers or containers to minimize any EMC interference.
• Tap the probe lightly on the bottom of the beaker to remove any
air bubbles which may be trapped inside the PVC sleeve.
• Turn the instrument on by pressing the ON/OFF key.
• For HI 8633 and HI 8734:
Take the temperature of the solution
with a ChecktempC or another accurate
thermometer.
Press the COND/TEMP key for HI 8633 or TDS/TEMP for HI 8734
to display the temperature and adjust the temperature knob to
that of the solution e.g. 20°C.

• For HI 8733:
Adjust the TEMPERATURE COEFFICIENT
knob to 2% to compensate for the
temperature effect of average solutions
(to determine exact value for a particu-
