Aquamaster Tools Combo Pen P110 Pro

The AD31 is a waterproof EC/TDS and temperature measuring device. The housing is fully sealed against moisture. All EC and TDS measurements are automatically temperature compensated, and the temperature values can be displayed in °C or °F. The EC/TDS conversion factor can be selected by the user, as well as the beta coefficient for temperature compensation. The devices can be calibrated at one point. The measurements are highly precise and feature a unique stability indicator directly on the LCD display. The models are also equipped with a low battery symbol that alerts the user when the batteries need to be replaced. The AD32P probe supplied with the measuring devices is interchangeable and can be easily replaced by the user. The encapsulated temperature sensor allows for quick and accurate temperature measurement and compensation.

Each measuring device is fully supplied with:

• AD32P EC probe
• 4 x 1.5 V button cell batteries
