28.3LPM Online Particle Counter OPC-6510DS

OPC-6510DS is a cleanroom airborne particle counter, it can accurately detect and calculate the number of different size particles in the air per unit volume. The device can simultaneously output the particle number of 5 channels of >0.3μm, >0.5μm, >1.0μm,  >5.0μm, >10μm in pcs/28.3L or pcs/m³. The screen can real time display the monitoring data, cleanroom ISO14644-1 2015 grade and alarm once the particle quantity exceeds the set threshold. The touch screen also supports setting the output unit, display channel, concentration alarm threshold, coefficient, language, work time, MQTT, etc.
