METHANE INDICATOR CMC5

    The methane indicator CMC5 is intended to give the light signal at reaching or exceeding of the two assigned thresholds of methane content in the environment, as well as for individual illumination of the working place in the coalmines with gas and dust hazard of any category.


  • The methane indicator CMC5 is integrated with the mining explosion-proof cap lamp.
  • The monitoring and warning about availability of methane in excess of the admissible standards, as well as the explosion-safety of the indicator are ensured by the special sensor, electronic devices and design of the casing parts.
