The Crowcon Xgard Type 2 is an Exd Flameproof toxic and oxygen gas detector using an electrochemical sensor within an Xgard enclosure, which also contains the amplifier/transmitter to provide a two-wire 4 to 20mA sink output.

Suitable for use with a range of cable glands; M20 or 1/2″ NPT or 3/4″ NPT. There is a choice of housing; durable aluminium with a tough polyester coating or 316 stainless steel for maximum corrosion resistance. All versions are suitable for deployment in harsh environments, such as offshore or in heavy industry- corrosion resistant.

Units can be installed on walls or ceilings, with three junction box choices—replacement sensors plugin.  Accessories are available for duct mounting, sampling applications and remote gassing – simple sensor checking.  In wash down areas or marine applications, splash guards and weatherproof caps are available.
