All conductivity and TDS readings are automatically temperature compensated (ATC),and temperature values can be displayed in °C or °F units.
The Conductivity/TDS conversion factor (CONV) can be selected at one point.
Measurements are highly accurate with a unique stability indicator right on the LCD.
The tester also features a low battery symbol which warns the user when the batteries need to be replaced.
The AD32P probe supplied with the meters, is interchangeable and can easily be replaced by the user.
