pH VALUES AT VARIOUS TEMPERATURES
For instance, if the buffer temperature is 25°C, the display should
show pH 4.0 or 7.0 or 10.0.
If the buffer temperature is 10°C, the display should show pH 4.0 or
7.0 or 10.1.

If the buffer temperature is 10°C, the display should show pH 4.0 or
7.0 or 10.1.
Note: The probe should be submerged approximately 4 cm (1½") into the
solution. The ChecktempC thermometer has to be located close to
the probe.
