Musktool-TG9 Duct CO2 Transmitter with Temp.&RH
overview
| In-duct real time detect carbon dioxide, with optional temperature and relative humidity. A special sensor probe with the water-proof and porous film can be easily installed into any air duct. LCD display is available. It has one, two or three 0-10V / 4-20mA linear outputs. The end user can change CO2 range which correspond with the analog output via Modbus RS485, also can preset the inverse proportion liner outputs for some different applications. |
