The Crowcon SafEye Quasar 900 is an open path detection system. It employs “spectral fingerprint” analysis of the atmosphere using the Differential Optical Absorption Spectroscopy (DOAS) technique. With a range from 7m up to 200m the Quasar 900 detects gas hazards in extremely harsh environments where dust, fog, rain, snow or vibration can cause a high reduction of signal.
The Xgard range of gas detectors has been specifically designed to meet your requirements. The dangers presented by toxic and flammable gases as well as oxygen deficiency vary with each application.
Xsafe is a non-certified low cost catalytic bead type detector with 3-wire 4-20mA or mV bridge output.
