On-line Oil Liquid Particle Counter

The LPC-M on-line particle counter adopts the counting principle of the photoresistance (shading) method specified by the International Hydraulic Standards Committee, and is specially used for on-site on-line measurement and oil pollution level detection device. It has the advantages of small size, light weight, fast detection speed, high precision, good repeatability, etc., and can work under harsh conditions such as high temperature and high pressure. Suitable for engine oil, gear oil, transformer oil (ie insulating oil), hydraulic oil, lubricating oil, synthetic oil, water-based (water-based hydraulic oil, water glycol, etc.), alcohols, ketones, etc. Solvents can be widely used in aerospace, petrochemicals, transportation ports, iron and steel metallurgy, automobile manufacturing and other fields.
