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 probe can be inserted directly into the process pipe through a ball valve without draining the oil in the system.
The MM70 also supports the use of Vaisala's humidity, dew point, and carbon dioxide probes, making it a versatile investment applicable to several multi-parameter applications. Two probes can simultaneously be connected to the MM70.
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.

No reference oil needed for recalibration.
No need to drain the oil. The probe can be inserted directly into the process pipe through a ball valve without draining the oil in the system.
Supports the use of Vaisala's humidity, dew point, and carbon dioxide probes, making it a versatile investment applicable to several multi-parameter applications. One or two probes can be connected simultaneously.
Choosing the most suitable measurement instrument requires an understanding of the factors that contribute to the uncertainty of a measurement. This in turn provides an understanding of what is stated in the specifications – and what is not.
Powercor has been running a program of on-line moisture monitoring on transformers using both permanently installed and portable moisture in oil probes, including the Vaisala HUMICAP® Moisture Meter MM70.
