The STATUS FGD3 Methane (CH4) Fixed Gas Detector are intrinsically safe products for use in Zone 1 & 2 hazardous areas when used in conjunction with an intrinsically safe supply. Features include light weight, flame retardant case, multiple plug-in replaceable sensor options and single operator calibration. The detector heads use either a two-wire or three-wire connection depending on sensor type. Where necessary the third connection provides power for infrared and pellistor sensors and associated circuitry.

A version of the STATUS FGD3 Methane (CH4) Fixed Gas Detector Infrared with metal enclosure is also available. This version is housed in a cast aluminium enclosure to provide higher RFI immunity where high power portable radios are used in close confines. The enclosure is plated and painted in order to withstand harsh environments. An optional weather guard is available for installations exposed to the atmosphere or contaminants and reduces the possibility of water or other contaminants entering into the gas sensor thereby improving the overall reliability of the gas detector in harsh environments
