The temperature probe that is supplied with the HI 9224 and HI
92240 is a liquid/general purpose probe.
Taking a temperature measurement with HI 9224
and HI92240 is very easy.
Press the "RANGE" key to get into the °C mode.
The temperature value and the "°C" symbol
will be displayed on the primary display.
Secure the connection of the probe to the top of
the meter, and take the measurement (allow 1
or 2 minutes for the temperature to stabilize).

Note: When taking pH measurements, in order
to have the best accuracy and proper
temperature compensation, immerse the
temperature probe as close as possible to
the pH electrode.

To take pH measurements, simply submerge the
bottom 4 cm (1½") of the electrode and the
temperature probe in the reading solution to be
tested, stir gently and allow for the electrode to
adjust and stabilize.
For greatest accuracy, it is recommended to calibrate the meter
regularly (see page 13).
The pH reading of any sample is directly effected by temperature. In
order for the meter to measure the pH accurately, it must know the
temperature. To use the meter's Automatic Temperature Compensa-
tion capability, submerge the temperature
probe in the sample as close to the electrode
as possible. If the temperature probe is discon-
nected, the meter assumes that the temperature
of the solution is 25°C (default temperature) and
the "°C" symbol blinks. Press the RANGE key to
show the temperature reading.
If measurements are taken successively in different samples, it is
recommended to rinse the electrode thoroughly with deionized water
or if not available tap water first and then with some of the next
sample to condition the electrode before immersing it in the sample.
