Airborne Particle Counter NAPC-300

Airborne Particle Counter NAPC-300 is a type of dust particle counter designed to measure the number and size distribution of dust particles in clean room. It can measure the class 100 to 300 k environment. The instrument uses the laser diode as the light source, LCD panel displays, six different size ranges simultaneously and the built in printer can print count results. Also the counter store 1000 samples data. Software creates data files for viewing or export to EXCEL sheet to computer.
