ISO4406 NAS1638 GJB420A/B Portable Oil Particle Counter Hydraulic Oil Cleanliness Tester
Portable Oil Particle Counter
I. Introduction:
Portable Lubricant Oil Particle Counter is photoresist (light shading) counting principle specified by the International Hydraulic Standards Committee.It is mainly for laboratory or on-site testing the degree of particle contamination and moisture in the oil. It has the advantages of small volume, light weight, fast detection speed, high precision and good repeatability, and can work under high temperature and high pressure environment. It is applicable for the measurement of engine oil, gear oil, transformer oil (i.e. insulating oil), hydraulic oil, lubricating oil, synthetic oil and other oils, widely used in aerospace, petrochemical, transportation ports, steel metallurgy, automobile manufacturing and other fields.
II. Main Features
