Teledyne Detcon FP-700 Gas Detector

Feature & Principle

It is a smart combustible gas detector of Teledyne Detcon 700 series, adopting catalytic bead detection principle. When combustible gas contacts the catalyst bead, oxidation reaction occurs and causes resistance change, the internal circuit converts the signal into LEL concentration value. It supports non-intrusive magnetic calibration, built-in LED display for concentration and fault status. The sensing probe is field pluggable and replaceable, with anti-poisoning design, encapsulated electronic circuit and surge protection, suitable for long-term stable monitoring in corrosive, humid and vibration hazardous sites.
