AD11 and AD12 are the most advanced microprocessor based Waterproof pH/Temp pocket testers in the market. Fast, stable and precise, these testers are for users that require the greatest accuracy. Simple user-replaceable pH/Temp probe: just unscrew the plastic ring on the top of the electrode and replace it with a new one!

2 rows display LCD (reads both pH and temperature measurements) and built-in HOLD function that freezes the display for easy and accurate recording. Other features such as stability indicator, automatic calibration and automatic temperature  compensation make these waterproof pocket testers a must-have in a variety of industries. The modular design allows to replace  the electrode in a fast and simple way.

The testers are supplied in a box complete with protective cap, 4 x 1.5V batteries and user manual.

AD31 and AD32 are waterproof Conductivity, TDS and temperature testers. 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 at one point. Measurements are highly accurated with a unique stability indicator right on the LCD.  The models are also provided with a low battery symbol which warms the user when the batteries need to be replaced. The AD32P 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.

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 onepoint, 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.
