General features of the probe:

The probe measures the residual oxygen content in a measuring chamber at the end of the measuring gas fitting. 
The probe signal can be tapped off as a voltage. The probe is heated with a constant voltage. For supplynig the heating only power supply inits approved by MESA may be used. 
The quantily of gas passing the probe should be within a range of 20...50 l/h. 
Too much gas volume can change the highly constant probe temperature, which results in a falsification of the measured value. 
Every probe includes two contants ( K1 and K2 ). These constants must be entered in the measuring instruments ( e. g. intelligent measuring transmitter MP 47, Carbomat-M ). Otherwise it will result in a wrong measurement. 
Two CO maesuring range can be choosen, 0...50 % CO or 0...100 % CO. 
The CO-modul is controlled to a constant temperature of about 42 °C by peltier elements, to avoid condensate.
