Airborne Particle Counter NAPC-401

Airborne Particle Counter NAPC-401 is used to measure dust particles inside a clean room environment. Its laser particle counter uses a semiconductor laser with a light source and a large touch-screen display. It is small in size and with light weight, highly precise and easy to operate. The microprocessor can control, store and print the measurement results, the test environment is very clean convenient. In addition, special software can be downloaded via computer to store the data. A high volt DC power source is applied which results in maximum consumption that is around 80 W.
