The HSY-432C fully automatic desktop oil contamination particle size analyzer is an upgraded product in the desktop series. This instrument is developed based on standards such as GB/T 18854-2002 (ISO11171-1999), utilizing the light obstruction (extinction) method for counting principles. It fully complies with relevant national military standards, national standards, and international standards. It provides fast, accurate, reliable, and repeatable test results, along with comprehensive contamination monitoring analysis reports. It is suitable for detecting particle contamination in hydraulic oil, lubricating oil, fire-resistant fluid, insulating oil, and turbine oil. It can be widely applied in industries such as aviation, aerospace, power generation, petroleum, chemical, transportation, ports, metallurgy, machinery, and automotive manufacturing.
