    Tips: How to use a laser particle counter?

    The method of using the laser particle counter is very simple. First determine the number of test points according to the area of the clean room and evenly distribute the test points in the clean room, then set the parameters of the particle counter such as measurement time, measurement unit, flow rate, etc. Point on a plane with a height of 1 to 1.2 meters from the ground, and finally start the test sampling and record the data.
