Hand-Held Moisture and Temperature Meter for Spot-Checking in Oil MM70

Reliable MM70 is an ideal tool for the preventive maintenance of oil-filled systems. The water activity measurement indicates the margin to free water formation, which causes severe problems in lubrication systems. Excellent pressure and temperature tolerance.

The optional MI70 Link Windows® software in combination with a USB connection cable is used to transfer logged data and real time measurement data from the MM70 to a PC.
