Laser Particle Counter NLPC-200

Laser Particle Counter NLPC-200 is a device used to measure the cummulative and differential size distribution of dust particles per unit volume in clean environment. Using the laser diode, the instrument measures the light that is redirected or absorbed by the particle. A highly accurate built-in sensor displays the measurement on a well-lit LCD display along with temperature and humidity readings. Designed with 6 measurement channels, laser particle counter is a perfect tool for measuring and monitoring airborne contamination sources in hospitals or healthcare facilities.
