Vaisala MMP8 | Moisture in Oil Probe | ±0.02 aw, -70 to +180 °C
The Vaisala MMP8 moisture-in-oil probe uses the HUMICAP 180L2 sensor to measure dissolved moisture in transformer, hydraulic and lubricating oils as water activity (aw), relative saturation (%RS) and temperature. It can also give ppm concentration for specific oils.
- Accuracy ±0.02 aw / 2 %RS
- Temperature range -70 to +180 °C
- Traceable calibration certificate, as recommended by CIGRE
- Works with Indigo transmitters or standalone via Modbus RTU
- Measures relative saturation (%RS) and water activity (aw)
