The device is designed to control the purity of liquids directly in operating equipment; it is also possible to analyze samples from containers.
The measurement principle incorporated in the PCM400 device allows avoiding distortion of the results of measuring the cleanliness class in the presence of water, air in the liquid and a high level of pollution. In the PCM 400W version, the device is equipped with a built-in sensor for determining the content of water dissolved in the working fluid (mineral / synthetic oils, non-combustible fluids based on phosphoric acid esters, petroleum-based fluids). The measurement results are displayed: in the form of% of liquid saturation with water or in ppm (for certain liquids).
