Download Datasheet

SENSOR FEATURES
  • Sensor designed to reliably detect H2S at concentrations from 0.15-100 ppm.
  • Rugged sensor undamaged by exposure to temperature and humidity extremes.
  • Fast response and complete recovery after H2S exposure.
  • Large, stable, easy to measure resistance change on exposure to H2S.
  • Sensor response is stable (does not go to sleep).
