ISO4406、NAS1638 Measurement of oil contamination level detection online device

On-line particle counter is the adoption of the International Hydraulic Standard Committee specified photoresist (shading) method counting principle, specifically for on-site online measurement, oil contamination level detection device. It has the advantages of small volume, light weight, fast detection speed, high precision, good repeatability, etc., and can work in 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 fluids, can be widely used in aerospace, petrochemical, transportation ports, iron and steel metallurgy, automobile manufacturing and other fields.
