The TX Carbon Dioxide Sensors with Transmitters (RS485) incorporate a high-performance controller supporting various types of carbon dioxide sensor modules.

The TX CO2 series, combines the GSS ExplorIR®-M Carbon Dioxide Sensor with a PCB that provides RS485 Modbus RTU interface, 24VDC operation, and a 4-20mA industry standard interface.

With the 4-20mA industry standard interface, it gives the ability to zero and span calibrate the sensor. It is also mounted on a 30mm PCB to fit industrial and many other applications.
