Due to the fact, that CO2 is an important indicator for the quality of air in rooms, it‘s super important to measure the CO2 content. The recommended CO2 limit value for ambient air is 1000 ppm. An exceeding of this limit causes tiredness and a loss of concentration.

The high quality and precise CO2-transducer works according to the infrared principle (NDIR). An auto-calibration procedure compensates aging effects and is responsible for an excellent long term stability of this CO2 transducer. Due to the freely adjustable output signal the transmitter could be used for nearly each existing controller input etc. Additionally, there is a local display which shows beside the actual CO2 concentration, the minimum and maximum values as well as an optical alarm.
