MM70 Portable Humidity and Temperature Meter for checking Oil errors

MM70

Vaisala

New

Convenient
Reference oil is not required for recalibration.

Easy online process check
No need to drain the oil. The probe can be inserted directly into the process pipeline through a ball valve, without draining oil into the system.

Economical operation with multiple probes
Compatible with carbon dioxide, humidity and dew point probes, making it a versatile investment applicable to various multi-parameter applications. One or two probes can be connected simultaneously.

Instrument for: Oil (Temp & RH)
Function: Oil Filled Systems
Parameters Measured Water activity

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

- Independent measurement of oil type, age and temperature: indicates oil saturation margin
- Online process check through ball valve, no need to drain oil
- Robust and reliable construction.
- Multithreaded operation; dew point and CO2 probes can also be connected
- HUMICAP® Sensor - Proven Field Performance Since 1973
