Eddie Production and Supply BMK-II Portable Coal Mine Gas Explosibility Tester welcomes inquiries.
The BMK-II Portable Coal Mine Gas Explosibility Tester is an intrinsically safe and flameproof portable instrument used in coal mines underground. It is carried by mine rescue team members into mining areas to monitor whether the surrounding gas composition poses an explosion risk. It can also be used by firefighting personnel during the handling of spontaneous combustion or unsealing of fire zones to monitor the concentration of methane and oxygen in the surrounding environment or sealed areas. The BMK-II Portable Coal Mine Gas Explosibility Tester directly displays the concentration values of O2, CH4, CO, and ambient temperature on its LCD screen, along with an "explosion triangle" graph and the coordinate points formed by each gas component. When approaching or reaching the alarm threshold, the instrument emits both audible and visual alarms.
