Online Oil Particle Counter HM-YZ20

The online oil particle counter is a device specifically designed for detecting the level of pollutant particles in liquids, based on the counting principle of the light blocking method specified by the International Hydraulic Standards Committee and developed in accordance with national and international standards such as GB/T 18854-2002 (ISO11171-1999). Can provide fast, accurate, reliable, and reproducible detection results. Easy and convenient to operate, suitable for online monitoring of various oil systems. Two (or more) slave machines can also be connected to the same host or platform for comparative testing, with simple operation and flexible combinations. It can be widely used in aviation, aerospace, power, petroleum, chemical, transportation, ports, metallurgy, water treatment, machinery, automobile manufacturing and other fields.
