Carbon Dioxide Transmitter with Temp.&RH

Short Description:

Model: TGP Series
Key words:
CO2/Temperature/Humidity detection
External sensor probe
Analog linear outputs

It is mainly used in the application of BAS in industrial buildings to real time monitoring carbon dioxide level, temperature and relative humidity. Also suitable for applications in plant areas such as mushroom houses. The lower right hole of the shell can provide expandable use. The external sensor probe to avoid internal heating of the transmitter from affecting measurements. White backlight LCD can display CO2, Temp and RH if required. It can provide one, two or three 0-10V / 4-20mA linear outputs and a Modbus RS485 interface.
