The AlphaSense H2S-A1 Hydrogen Sulfide Sensor is designed to detect low levels of hydrogen sulfide in ambient air using well-known fuel cell technology.

This 20mm diameter sensor is the industry standard size for portable gas detectors.

With very high sensitivity and low zero, accurate and stable readings are possible when measuring current concentration ranges at the parts per million level.

  • 0 to 100ppm H2S sensor
  • Does not require calibration
  • Up to 2 year lifespan
  • Small, compact and maintenance free
