Duct Air Quality CO2 TVOC Transmitter

Short Description:

Model: TG9-CO2+VOC
Key words:
CO2/TVOC/Temperature/Humidity detection
Duct installation
Analog linear outputs
Real time detect carbon dioxide plus tvoc (mix gases) of the air duct, also optional temperature and relative humidity. A smart sensor probe with the water-proof and porous film can be easily installed into any air duct. LCD display is available if required. It provides one, two or three 0-10V / 4-20mA linear outputs. The end user can adjust CO2 range which correspond with the analog outputs via Modbus RS485, also can preset the inverse proportion liner outputs for some different applications.
