SENSOR FEATURES:
• Sensor designed to reliably detect H2S at concentrations from 1-100 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.
• Preliminary studies indicate sensor response is stable (does not go to sleep).

Concentration H2S (ppm)
Linearity of sensor response to H2S. Different cylinders used for low and high
concentration testing.
Sensor response curves for varying H2S concentrations. H2S introduced at t=300 seconds, and removed at t=900 seconds.
Electrical Characteristics
The electrical properties below are typical for the H2S Sensors. If the actual values differ, the customer will be notified with the shipment. Circuits are available that will be preset to the correct values.
