LWT-2A oil particle counter is based on GB/T 18854-2002 (ISO11171-1999) and other standards. It is developed by adopting the counting principle of photoresist (shading) method, which is in full compliance with the corresponding national military standard, national standard and international standard. It can provide fast, accurate, reliable and repeatable test results and complete pollution monitoring and analysis report, which is applicable to the detection of particle contamination of hydraulic oil, lubricating oil, anti-fuel oil, insulating oil and turbine oil. It can be widely used in aviation, aerospace, electric power, petroleum, chemical industry, transport, harbour, metallurgy, machinery, automobile manufacturing and other fields.
