Description
The PMOS Outside Particulate Matter Sensor uses an optical sensor based on laser scattering principles and features innovative contamination resistance technology to perform highly accurate and reliable PM measurements. The replaceable sensor measures particles of PM2.5 and PM10, with a continuous operation lifetime of more than 8 years. The sensor will provide long-term reliability and high resolution particle size binning for the detection of environmental dust and other particles.
NOTE: Please contact us if you are interested in Modbus RTU, BACNet MS/TP Communication or the Relay output option.
