Greystone - Model PMDT Series -Duct Particulate Matter Sensor

The PMDT Duct 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 PM1.0, PM2.5, PM4.0, or 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. A hinged and gasketed Polycarbonate enclosure is included for ease of installation.
