Det-Tronics 006824-001 (model CGSS1A6C2R1X) is a CGS catalytic combustible gas sensor. A matched pair of pellistor beads, one active and one reference, measures flammable gas in the % LFL range, and the sensor detects virtually all combustible gases, including hydrogen. It connects to a Det-Tronics transmitter or controller.
