The HSY-432G Portable Oil Contamination Particle Size Analyzer is an instrument developed in accordance with national and international standards such as GB/T 18854-2002 (ISO11171-1999), specifically designed for detecting contamination levels in oils. It is suitable for on-site and laboratory contamination testing of hydraulic oil, lubricating oil, shale oil, transformer oil (insulating oil), turbine oil (turbine oil), gear oil, engine oil, aviation kerosene, water-based hydraulic oil, phosphate ester oil, and other oils. It can also be installed in various hydraulic transmission systems, oil purifiers, cleaning machines, and test benches to enable online monitoring of oil cleanliness. It is widely applicable in industries such as aerospace, power, petroleum, chemical, transportation, ports, metallurgy, machinery, and automotive manufacturing.
