LWT-5 oil particle counter is the upgraded product of LWT desktop series, the instrument is based on GB/T 18854-2002 (ISO11171-1999) and other standards. Adopting the counting principle of photo-resistance (shading) method, it is fully compliant with the corresponding national military standards, national standards and international standards. It can provide fast, accurate, reliable and repeatable test results and complete pollution monitoring and analysis report, which is suitable for 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.
