  • The functionality of a MOX gas sensor is based on the conductivity-change of the gas-sensitive MOX-semi conductor layer/s at gas exposure. Öffnet internen Link im aktuellen Fenster...
  • Various sensor cases:
    • Gas sensor elements in a TO39-case (socket with chip + specific T/2T-cap with filter):
      • 4-Pin-case for single and multiple gas sensor elements
      • 8-Pin-case for gas sensor arrays
    • Single and multiple gas sensor elements in iso-thermic 4-Pin-SMD-cases
