Gascheka self-calibrating multigas detection system can proactively shutdown electric/IC powered industrial equipment before ignitable levels of flammable gas/vapors develop around equipment. It does not rely on user’s ability/judgment to turn off equipment when there is accidental spill/release of flammable gas, vapors, or liquids. Designed to be installed on equipment that is not EX certified, detector is used in and around facilities that handle Class 1 flammable gas and liquids.
