• • Monitoring Air Quality

• “Particulate matter” (PM) is the general term used to describe solid particles and liquid droplets found in the air. The PM2.5 series of transmitters are designed to detect Particles less than 2.5 μm in diameter include smoke, smog, bacteria, -ne dust and liquid droplets, and report the particle concentration of the monitored environment. The unit utilizes a laser particulate matter sensor to detect particle sizes from 0.3 ~ 2.5 μm. The sensor has good long-term stability with an accuracy 10% reading or 10 μm/m3. The room unit features fi¬eld selectable outputs, 4-20 mA, 0-10 VDC, and Modbus RTU (RS485), relay, and display. The sensor has two jumper selectable working modes for monitoring PM. The Normal Mode monitors the environment continuously and Auto Mode reduces the measuring time to extend service life. The sensor is sent default in Auto Mode.
  
  The PM Series are covered by ACI's two (2) Year Limited Warranty, which is located in the front of ACI's Sensors & Transmitters catalog or can be found on ACI's web site, which is: www.workaci.com.
