AD31 Professional Waterproof EC/ TDS/ Temp Pocket Tester – Low Range
The AD31 is a waterproof Conductivity, TDS and temperature tester. The housing has been completely sealed against humidity. 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 by the user, as well as the coefficient ß (BETA) for temperature compensation. The instruments can be calibrated at one point. Measurements are highly accurate with a unique stability indicator right on the LCD. The models are also provided with a low battery symbol which warns the user to replace the batteries.
