Online oil particle counter YT-YZ20

The online particle counter is a device specifically designed for on-site online measurement and detection of oil contamination levels, using the light blocking counting principle specified by the International Hydraulic Standards Committee. It has the advantages of small size, light weight, fast detection speed, high accuracy, and good repeatability, and can work under harsh conditions such as high temperature and high pressure. Suitable for all transparent solvents such as engine oil, gear oil, transformer oil (i.e. insulation oil), hydraulic oil, lubricating oil, synthetic oil, water-based (water-based hydraulic oil, water ethylene glycol, etc.), alcohols, ketones, etc. It can be widely used in aerospace, petrochemical, transportation and port, steel metallurgy, automobile manufacturing and other fields.
