Crowcon Flamgard Plus Fixed Gas Detector

The Crowcon Flamgard Plus is a flameproof (Ex d) fixed flammable gas detector that uses proven pellistor (catalytic bead) technology for the detection of combustible gases and vapours. Designed for operation in harsh industrial and offshore environments, the Flamgard Plus incorporates a local display, non-intrusive calibration facilities, and a standard 4-20 mA output for easy integration with gas detection control systems.

The detector is capable of monitoring a wide range of flammable gases, including hydrocarbon gases, hydrogen, aviation fuel vapours, and leaded petrol vapours.
