Det-Tronics 006824-003 (configuration CGSS1C6C2R1X) — CGS catalytic combustible gas sensor in a one-piece 316 stainless steel housing.
The CGS uses a pair of computer-matched pellistors (beads). When flammable gas is present, the active bead catalyzes the gas while the reference bead balances the reaction and compensates for normal ambient changes. The sensor detects virtually all combustible and flammable gases, including hydrogen, in the LFL range, and must be connected to a Det-Tronics combustible gas transmitter or controller.

FAQ
Can the CGS be used on its own?
No. It must be used with a Det-Tronics transmitter or controller such as the FlexVu UD10, FlexVu UD30, Infiniti U9500 or Model 505.
Will it detect hydrogen?
Yes. The CGS can detect virtually all combustible and flammable gases, including hydrogen.
How long does the sensor last?
Typically 3 to 5 years when the environment is free of substances and conditions known to harm catalytic sensing elements.
How often should it be calibrated?
30 days after initial calibration and every 90 days after that, or as the application and environment require.
