The GTO-CO2 is the carbon dioxide concentration transmitter with linear 4 – 20 mA output.

It is delivered with a standard range of 0.2 – 5%, however, it is possible to deliver it with a user-specific range on a request. The measuring element is an infrared sensor complemented with electronics for the signal adaptation. The 24 Vdc power supply input and the current signal output are connected via DIN 43650 connector. The transmitters are mounted on a wall. Infrared sensors are known as highly precise and reliable. The transmitter is designed to monitor CO2 concentration in working environment, controlled ventilation systems, in air-conditioning spaces and to control greenhouse or protective atmospheres.
