ZWKL-3A particle counter is developed using the light shading method (also referred as light blockage method ), and is used to detect the size and number of solid particles in liquid. It can be widely applied to aviation, aerospace, electric power,petroleum, chemistry, transportation, port, metallurgy, machinery, automobile manufacturing and other fields. Specifically, it tests pollution level of solid particles in oil fluid such as hyd raulic oil, lubricating oil, transformer oil (insulating oil),steam turbine oil (turbine oil), gear oil, engine oil, aviation kerosene and water-based hydraulic oil and detects insoluble particles in organic liquid and poly mer solution.
