Temperature
The temperature has a direct influence on pH. This option allows the user to choose the temperature source and
units, as well as the desired manual temperature for manual temperature compensation mode.
Temperature Source
(HI 4222 only)
If using a temperature probe, Automatic Temperature Compensation will be performed relative to the displayed
temperature, with the “ATC” indicator displayed on the LCD. For HI 4222 only, the ATC option can be selected for
Channel 1 or Channel 2, in accordance with the active channel utilizing a probe, or for both channels if two
temperature probes are used. If no temperature probe is detected, Manual Temperature Compensation will be
performed, with the “MTC” indicator on the LCD.
Temperature Unit
Accessing this option, the desired temperature unit can be chosen (Celsius, Fahrenheit or Kelvin degrees) and the
meter will automatically make the conversion for the selected unit.
Manual Temperature
If no temperature probe is connected, the desired temperature can be set manually. The default setting is 25°C.
If the measured temperature is different, the value can be manually adjusted in order to obtain an accurate pH
reading.
