The Vaisala HUMICAP® Hand-held Moisture Meter for Oil 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.

  • Measurement independent of oil type, age and temperature - indicates margin to oil saturation
  • In-line process checking through ball valve, no need to drain the oil
  • Rugged and reliable construction
  • Multiprobeoperation; dewpoint and CO2 probes can also be connected
  • Vaisala HUMICAP® Sensor - proven field performance since 1973
