Application

LPC-O online particle counter is developed by the International Hydraulic Standards Committee to determine through the principle of photoresist (shading) method, according to GB/T 18854-2002 (ISO11171-1999) and other national and international standards to measure the concentration of contaminated particles in liquids. The instrument provides fast, accurate, reliable, and repeatable test results. Simple and convenient to operate, it is suitable for online monitoring of various oil systems. It is also possible to connect two (or more) to the same equipment or platform for comparison test, which is simple in operation and flexible in combination. It is widely used in aviation, aerospace, electric power, petroleum, chemical, transportation, port, metallurgy, water treatment, machinery, automobile manufacturing and other fields.

Features

1.Adopts the principle of light resistance (shading) method specified by the International Hydraulic Standards Committee;

2.High-precision laser sensor with wide test range, stable performance, low noise and high resolution;

3.High precision double plunger pump with stable injection speed and high sampling accuracy;

4.Pressure relief device can be equipped for online high pressure test;
