Intrinsically Safe Stationary Metanoid IMS-1

The intrinsically safe IMS-1 Stationary Methane Meter is a device designed for continuous measurement of methane concentration in the atmosphere in the range from 0 – 100% in methane and coal dust explosive zones.

The IMS-1 methane meter is equipped with two deactivation outputs with independently set operation thresholds so that it is possible to automatically deactivate electricity if the permissible concentrations are exceeded. The device is also equipped with two two-state inputs allowing the reading of external shutdown signals.
