Laser Particle Counter NLPC-203
Laser Particle Counter NLPC-203 is a hand-held, battery-operated device used to measure the particle concentration in clean rooms and workplaces, both solid and liquid particles using laser technology. Designed with TFT LCD display, it provides fast and precise readings of particle mass concentration along with air temperature, dew point and relative humidity. These devices are extremely helpful to determine leak tests of HEPA filters, monitoring of filters in room ventilation systems, assessment of airborne dust concentration indoors, etc.
