HML and HML-N carbon monoxide transmitters are designed for detecting carbon monoxide in underground parking garages and parking halls. The measuring cell is an environmentally friendly electro-chemical cell with a long life, good long term stability and high accuracy. As the sensor is heated the transmitter is working also in temperatures > -30°C. The output of 0...10 V or 4...20 mA is available on the ranges of 0...100 or 0...300 ppm CO concentration for controlling ventilation.
