The LPC-P50 Portable 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.
