By adopting advanced electrical technology and electrochemical sensor, Carbon Monoxide Detector detector KD-106C/D has high sensitivity and without misinformation. It can be used to detect the CO both at home and in the factory. The detector makes a linear voltage signal through directily react with the CO in the air in order to detect the CO. It will give both sounds and light signal once the density of CO in the air is up to a certain degree, to inform you to take measure in time.
