Carbon Monoxide/ Hydrogen Sensors are specially designed for medium and small combustion systems. These Carbon Sensors provide a current signal for COe and doesn’t need any reference air. These Carbon Sensors are high-resolution measuring system for the detection of small concentrations of COe in the range of 0 - 3000 ppm. Carbon Monoxide/ Hydrogen Sensors are available in two different housings, which are optimized for the respective requirements.
