ADWA AD32 Professional Waterproof Conductivity-TDS-Temperature Pocket Tester with replaceable probe


Automatic temperature compensation; Range(EC): 0.00 to 20.00 mS/cm; Accuracy(EC): ±2% f.s; Range(TDS): 0.00 to 10.00 ppt; Accuracy(TDS): ±2% f.s

  • Parameters: EC(Conductivity), TDS, Temperature


AD32 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 instrument 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 when the batteries need to be replaced.
