CO is a type of colorless, flavourless and nonirritating gas, it can't be distinguishedby sensing. So it is very important to install a CO detector. By adoptingadvanced electrical technology and electrochemical sensor, CO detector KD-106Chas high sensitivity and without misinformation. It can be used to detect the COboth at home and in the factory. The detector makes a linear voltage signal throughdirectly react with the CO in the air in order to detect the CO. It will giveboth sounds and light signal once the density of CO in the air is up to a certaindegree, to inform you to take measures in time. producing area:China payment:T/T 30% deposit, L/C at sight
