Both sides of the disc are coated with porous metal electrodes.
  • Page 12 Instruction Manual IM-106-880, Rev 1.0 OCX 8800 January 2007 The catalyst is specifically designed to detect carbon monoxide (CO), but the sensor responds to other combustible gases. The sensor is calibrated using CO, thus the output should be expressed in terms of CO. However, since the sensor detects other combustible gases, the output cannot just be labeled CO.
