The particle detector/portable particle counter uses the International Hypothetical Retardation (Frost) method of International Hydraulic Standards and is designed for rapid detection of the level of contamination of fluids in the field. They have the advantage of small size, light mass, fast speed, high accuracy and good repetitiveness, and can work under high temperature and high pressure, among other conditions. Microwater sensors and temperature sensors are built in and can be detected with water content and fluid temperature at the same time as contamination. They apply to oils such as engine oils, gear oils, transformer oils (i.e., insulation oils), hydraulic fluids, lubricants and synthetic oils, and are widely applied in areas such as aerospace, petrochemicals, traffic ports, steel metallurgicals and car manufacturing.
I. Particle detector/portable particle meter instrument characteristics
