ADWA AD33 Professional Waterproof Conductivit-Temperature Pocket Tester with replaceable probe


Automatic temperature compensation; Range: 0 to 1999 µS/cm; Resolution: 1 µS/cm; Accuracy: ±2% f.s.

  • Parameters: EC(Conductivity), Temperature


AD33 is a waterproof Conductivity tester, that also measure temperature. The housing has been completely sealed against humidity. All Conductivity readings are automatically temperature compensated, and temperature values can be displayed in °C or °F units. Conductivity calibration is automatic at one point, while temperature range is factory calibrated and can only be adjusted by the user. This model is provided with an auto-off feature that turns them off after 5 minutes of non-use. Moreover, when batteries become too weak to ensure reliable readings the meter automatically turns off.
