Explosion-proof detector

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 working principle of the electrochemical sensor by diffusion reaction directly with carbon monoxide gas in the environment produces a linear change of the current signal, the sampling, filtering amplification, analog to digital conversion, the software processing and display of carbon monoxide gas in the LED screen concentration. 2, 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.
