Online oil contamination detection instrument

The HM-YZ20 online oil contamination detection instrument is a device specifically designed for detecting the level of pollution particles in liquids, using the counting principle of the light blocking (shading) method specified by the International Hydraulic Standards Committee and based on 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 combination. It can be widely used in aviation, aerospace, power, petroleum, chemical, transportation, ports, metallurgy, water treatment, machinery, automobile manufacturing and other fields.
