Flammable Gas Alarm

CTH1000 coal with carbon monoxide measuring device is a single chip using imported electrochemical sensors and new all-digital microprocessor system gas detection instruments, can be done without opening the cabinet calibrated. With sound and light alarm, zero tracking, low overall power consumption, high precision, long life, beautiful appearance, easy to carry. --- Wxm 1, the structure of the carbon monoxide was measured mainly by electrochemical carbon monoxide sensor, digital control / mask socket, power outlet, the battery pack, charging screws, barrier, buzzer, transom, rings, alarm diodes, circuit boards, battery cover, mask, rings components. 2, the working principle of the electrochemical sensor by diffusion reaction ramping current signal directly in the environment of carbon monoxide gas, the sampling, filtering amplification, analog to digital conversion, the software processing and display of gas concentration of carbon monoxide on the LED screen. 3, the main purpose of this instrument is widely used explosive mixture of flammable gases in the work environment of continuous monitoring of carbon monoxide gas concentrations in the coal mine, and when it reaches the set concentration alarm sound and light. 4, explosion-proof form type: Mine intrinsically safe; proof mark: ExibIMb 5, use environmental conditions ??? a) Operating temperature: 0 ℃ ~ 40 ℃; b) Relative humidity: ≤98%; c) atmospheric pressure: 86kPa ~ 116kPa. d) has a dangerous coal mine methane or coal dust explosion. e) Storage temperature -40 ℃ ~ 60 ℃.
