GC-4295 Portable Gas Chromatograph for Coal Mines

The GC-4295 is a portable GC that operates with only a single carrier gas, requiring no fuel or support gases, and features a built-in carrier gas cylinder. It is suitable for use in inert gas fire prevention and extinguishing operations to assess the development of sealed fire zones and the extent of fire extinction. The instrument can also monitor the inertization status of working areas, providing critical data to support firefighting measures and scientific basis for the unsealing of fire zones.
