Bmk-ii portable coal mine gas explosibility teste

  Bmk-ii portable coal mine gas explosibility tester is a mine intrinsically safe and flameproof portable instrument used in underground coal mines
Portable coal mine gas explosibility tester is used in underground coal mine
It is carried into the area by mine rescue team members to monitor whether there is explosion Za danger in the gas components around the working environment
It can also be carried by fire suppression personnel
In the process of dealing with natural fire or unsealing the fire area, the concentration values of gas and oxygen in the surrounding environment or air in the closed area
Bmk-ii portable coal mine gas explosibility tester directly displays the concentration values of O2, CH4 and CO and the ambient temperature values on the instrument LCD, and displays & ldquo; Explosion Za triangle & rdquo; The graph of and the coordinate points composed of various gas components
When approaching or reaching the alarm boundary, the instrument will send out audible and visual alarms at the same time
