KN-4406  Oil Liquid Particle Counter

Overview  

   KN-4406 Oil Liquid Particle Counter is a laboratory Instrument used to detect particle contaminants in liquids. It uses the principle of light blocking to detect and count the size of particles in liquids, thereby calculating the distribution and pollution situation of particles. The Instrument is equipped with pressurized and vacuum devices, which can effectively extract high viscosity detection liquids and eliminate microbubbles in liquids and is widely used for the detection of particle contaminants in liquid medium such as hydraulic oil, lubricating oil, transformer insulation oil, gear oil, aviation kerosene, organic liquid or polymer solution.
