catalytic bead
  • Description: Sensors are used to measure combustible gases that present an explosion hazard.
  • Synonyms: CFIHOS-60002552
electrochemical
  • Description: Works by allowing gases to diffuse through a porous membrane to an electrode where it is either chemically oxidized or reduced.
  • Synonyms: CFIHOS-60002551
holographic
