LWL-4 on-line particle counter is the adoption of the International Hydraulic Standard Committee specified photoresist (shading) method counting principle, specially used for on-site on-line measurement, oil contamination level detection device. It has the advantages of small volume, light weight, fast detection speed, high accuracy, good repeatability, etc., and can work under high temperature and high pressure and other harsh conditions. Applicable to engine oil, gear oil, transformer oil (i.e. insulating oil) hydraulic oil, lubricating oil, synthetic oil and other oils, can be widely used in aerospace, petrochemical, transport ports, iron and steel metallurgy, automotive manufacturing, oil filtration equipment and other fields.
