PTT-O Online Particle Counter

Application

PTT-O online particle counter is specially developed for the level of polluted particles in liquid using the photoresist (shading) method specified by the International Hydraulic Standards Committee and according to national and international standards such as GB/T 18854-2002 (ISO11171-1999). detection device. Provides fast, accurate, reliable, and repeatable test results. The operation is simple and convenient, and it is suitable for online monitoring of various oil systems. It is also possible to connect two (or more) slaves to the same host or platform for comparison tests, with simple operation and flexible combinations. It can be widely used in aviation, aerospace, electric power, petroleum, chemical industry, transportation, port, metallurgy, water treatment, machinery, automobile manufacturing and other fields.
