Model IR-700-CH Combustible Gas Sensor
Detcon Model IR-700-CH is a non-intrusive “Smart” sensor designed to detect and monitor combustible hydrocarbon gases in air over the range of 0-100% LEL using miniature non-dispersive Infrared Optical (NDIR) sensor technology. As compared to catalytic bead sensors, with NDIR there is no risk of sensor poisoning, no risk of high concentration saturation, and no need for O2 to be present. The plug-in, field replaceable detector features over-sized gold-plated connections that help prevent corrosion.
