The carbon monoxide gas detector is a portable detector for detecting carbon monoxide(CO) gas. It can continuously monitor the CO gas concentration in the surrounding environment, once the gas concentration reaches the level of the alarm, the alarm will sound and light. It is widely used in petroleum, chemical, coal, metallurgy, paper, fire, municipal, telecommunications, food, textile and other industries. Features: Carbon monoxide gas meter are widely used in science and industry to detect the concentration of carbon monoxide gas. Can continuously monitor the CO gas concentration in the surrounding environment. Sound alarm works when CO gas concentration reaches the level of the alarm. High precision portable CO gas tester with compact size and light weight is easy to carry and operate. Professional and accurate measurement. Large LCD color display and or switch. Can set concentration of alarm value. Auto power off in 10 minutes without any operation.
