The particle detector. How does the portable particle counter work?

　　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

　　1. Application of photoresist (shield) principles, use of high-precision laser sensors, small size, high accuracy and stable performance

　　2. For laboratory or on-site testing, pressure relief devices may also be selected for use in online high-pressure measurements for real-time monitoring of particulate contamination in oil-use systems

　　3. Exterior pressure chamber formation positive/negative, high viscosity sample detection and sample extraction

　　4. The built-in data analysis system, which displays real data on the particle sizes of the corridors and automatically determines the size of the sample

　　5. Implementation of 316L and PTFE materials for testing of various organic solvents and oils

　　6. Availability of volume and long-duration washing models for user-friendly use and maintenance of equipment

　　7, incorporated ISO4406, NAS1638, SAE4059, GJB420A, GJB420B, sit-in OCT17216, GB/T14039

　　8. Built-in calibration according to GB/T21540, ISO4402, GB/T18854 and other standards

　　The built-in data analysis system, which automatically determines the size of the sample according to the standard, has automatic data processing and printing functions.
