Vaisala HUMICAP Moisture in Oil Probe MMP8 enables fast and reliable measurement of moisture in oil. It uses the proven Vaisala HUMICAP® sensor that was developed for demanding moisture measurements in transformer and lubrication oils, hydraulic fluids, and other liquids.
MMP8 measures dissolved moisture in oil in terms of water activity (aw), relative saturation (%RS), and temperature (T). It also calculates ppm concentration for specific oils.
MMP8 is part of the Indigo family and is compatible with Indigo 200 Series Transmitters. It can be used with the Vaisala Insight PC software for data visualization, easy probe configuration and self-calibration.
