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

The MM70 is a reliable detector of moisture in lubrication, hydraulic and transformer oils. It is ideal for in-line moisture monitoring and locating problems in oil systems. Quick spot-checking is possible by inserting the probe directly into the process through the optional ball valve, without draining the oil in the system.
