TAKING CONDUCTIVITY MEASUREMENTS
Make sure that the meter has been cali-
brated before taking any measurements (see
page 18).

HI 933300 and HI 933301 are
auto-ranging conductivity meters, and the
reading automatically switches from one
resolution to the next, from pure water @
0.1µS/cm up to 199900 µS/cm.

Wait for a few minutes for the temperature
sensor to attain thermal equilibrium with the
test solution before taking the measurement.

If the temperature of the conductivity probe
and the solution is of considerable difference,
a longer time should be allowed before taking
readings.
