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.
