According to national and international standards, instruments specially used for the detection of pollution levels in oil are developed. Suitable for hydraulic oil, lubricating oil, rock 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 for on-site, Laboratory contamination testing. It can also be installed on various hydraulic transmissions, oil filters, washing machines, inspection test benches and other systems to realize online inspection of system oil cleanliness. It can be widely used in aerospace, electric power, petroleum, chemical industry, transportation, port, metallurgy, machinery, automobile manufacturing and other fields.
