Digital Moisture in Oil Immersion Probe up to 120 °C (248 °F)

MOP301 Digital Moisture in Oil Immersion Probe up to 120 °C (248 °F) The MOP301 reliably measures the moisture in transformer, lubrication or hydraulic oil as well as in diesel fuel. It is ideal for the preventive maintenance of equipment and machinery. Besides the accurate measurement of water activity (aw) and temperature (T), the MOP301 calculates the absolute water content of the oil (x) in ppm. The dynamic calculation is based on oil-specific solubility parameters. Measurement Performance The probe employs high end E+E humidity sensing elements with outstanding long term stability and high...

Features Measurement of water activity aw / water content x The moisture in oil can be expressed in absolute or relative terms. ▪ Water activity aw is the relative measure for moisture in oil. It represents the ratio between the actual amount of dissolved water and the maximum possible amount of dissolved water in the oil at a certain temperature. Independently of the oil type, the water activity shows how close to saturation the oil is at any moment in time. aw = 0 indicates completely dry oil, while aw = 1 fully saturated oil. MOP301 measures the water activity directly. ▪ The water content...
