HZJS-1 Portable particle counter adopts photoresist (shading) counting principle designated by international Hydraulic Standards Committee, specially used for fast detection device of oil contamination level on site. 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 and other harsh conditions. Built-in micro water sensor and temperature sensor can detect water content and oil temperature together with pollution degree detection. Suitable for transformer oil (insulation oil), hydraulic oil, lubricating oil, synthetic oil and other oil, can be widely used in aerospace, petrochemical, transportation ports, iron and steel metallurgy, automobile manufacturing and other fields.
