The HSY-432B fully automatic desktop oil contamination particle size analyzer is developed based on standards such as GB/T18854-2002-(ISO11171-1999). It adopts the light obstruction (extinction) method for counting principles, fully complying with corresponding national military standards, national standards, and international standards. It provides fast, accurate, reliable, and repeatable test results as well as comprehensive contamination monitoring analysis reports. It is suitable for detecting particle contamination in hydraulic oil, lubricating oil, fire-resistant fluid, insulating oil, turbine oil, and more. It can be widely applied in industries such as aviation, aerospace, power, petroleum, chemical, transportation, ports, metallurgy, machinery, and automotive manufacturing.
