Crowcon Xgard Gas Detector and Xsafe Gas Monitor

Crowcon Xgard fixed point gas detectors offer a comprehensive selection of gas leak detection instruments to meet diverse requirements of many industries and environments...

Crowcon's Xgard gas detectors lower operating costs and simplify maintenance of fixed gas detection.  Xgard's user friendly operations feature a universal junction box and replacement sensors that simply plug in. Xgard is available in Intrinsically Safe and Flammable versions.  This instruments wide range of sensors embrace 4 technologies: poison-resistant catalytic beads detect combustible gases; electrochemical sensors detect toxic gases and oxygen; thermal conductivity sensors monitor high-volume concentrations of certain gases mixed with air or other gases; and unique Sulphistors detect hydrogen sulphide at high temperatures and high background gas levels.

Xgard Features...

  • Wide range of accessories for harsh or wet environments
  • Rugged construction from A356 marine grade aluminum with a durable polyester coating
  • 2 year sensor available for oxygen monitoring, cutting replacement costs in half
