Waterproof Conductivity-TDS-TEMP Pocket Testers with replaceable electrode
AD33, AD34, AD35 and AD36 are waterproof Conductivity and TDS testers, that also measure temperature. The housing has been completely sealed against humidity.
All Conductivity and TDS readings are automatically temperature compensated, and temperature values can be displayed in °C or °F units. Conductivity (or TDS) calibration is automatic at one point, while temperature range is factory calibrated and can only be adjusted by the user. The AD33P probe supplied with the meters, is interchangeable and can be easily replaced by the user. The encapsulated temperature sensor allows fast and accurate temperature measurements and compensation.
To prolong battery life, these models are 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.
