705 Ammonia Sensor

Sensor Features

  • Detection range of <25 to 10,000 ppm ammonia (NH3).
  • High selectivity to ammonia.
  • Minimal response to changing environmental humidity.
  • Response is unaffected by prolonged exposures to or high concentrations of ammonia.
  • Sensor response is not affected by H2S.
