Manufactured by Det-Tronics, the Catalytic Combustible Gas (CGS) Detector is a poison-resistant, stainless steel sensor. Housed in a one piece design with an integral barrier and a 316 stainless steel enclosure, the model features a temperature range of –40 to 75 °F (–40 to 167 °C) and a resistance to EMI (electromagnetic interference). When used with a compatible transmitter, the sensor can detect almost all types of combustible gases in harsh environments. It is compatible with Det-Tronics' line of combustible gas transmitters and controllers.
