The PMRMC 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. 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.
