GENERAL:

Carbon monoxide (CO) is created by the combustion of carbon. DEPENDING on the effectiveness of the combustion (oxygen supply) and the temperature of the combustion more or less CO gas is created. The gas is inflammable and highly toxic. It is invisible, tasteless and scentless. 
Even smallest Concentrations are dangerous for humans! 
THEREFORE a directive exists in Germany, Which limits the maximum concentration of CO gas at work (MAK / AGW) to 30 ppm.

Due to the fact, did 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 1000ppm. An exceeding of this limit causes tiredness and a loss of concentration.
For measuring the CO2 concentration, GREISINGER electronics presents a high quality and precise CO2 transmitter, working gemäß 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 (4-20mA, 0-1V. 0-10V, etc.), 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 to optical alarm. If required, the CO2 transmitter Could be calibrated via buttons.
