Duct PM2.5 + Temperature Transmitter

No items found.


The duct mounting particulate matter and temperature transmitter (AI-PM2.5-DT) is suited for mounting in HVAC ducts in a rugged IP54-rated plastic enclosure with an adjustable duct clamp. Powered by the latest in sensing technology, the instrument leverages laser-scattering based sensors for the reliable measurement of PM2.5 and a digital sensor for the reliable measurement of temperature.

Applications include indoor air quality monitoring for fine dust pollutants in offices, retail spaces, educational institutions and is well suited with RS-485 Modbus communication for the monitoring of smart buildings and smart industrial applications.


  • Laser scattering principle based sensor for PM2.5
  • Digital sensor for temperature measurement
  • IP54 rated duct mounting ABS plastic enclosure
  • Optional RS-485 Modbus Communication
