NKEE On-line Oil Moisture Tester adopts VAISALA transmitter imported from Finland and is specially designed for measuring water in oil. It is an ideal choice for online detection of water content in lubricating oils and insulating oils with a precision of one part per million (PPM) to ensure the normal operation of equipment and machines. Moisture has a huge bad impact on the insulation characteristics of transformer oils, so continuous testing of transformer oils is very important. The NKEE series directly measures the aw and temperature T of water in oil. Using these parameters, the absolute moisture content (ppm) of the transformer oil can be calculated, and at the same time, the moisture content in other oils can be calculated by downloading specific parameters in the oil.
