1,intelligent,multifunctional and microminiaturized alarm detector 2,uesd for gas explosion,record data of its concentration. JCB-C31B methane detection alarm is an intellgent, multifunctional and microminiaturized alarm detector. It fits for the place where gas explosion may happen in coal mine, like excavating work place, electronic chamber and so on. It can record the data automatically each half an hour, while continuously detecting the methane concentration. Alarm will flash and sound, when the methane concentration exceeds the limit, and it will record the data each 10 seconds automatically at this time.The methane detection alarm adopts the microcomputer digital technique, its pile contains high energy rechargeable batteries which have the features of stable property, quick response, and high precision. Touch-tone switch with thin film, and four digital red tubes are used for demonstrating the data.
