Hydrogen Sulfide

000-H2S-B1Alphasense Hydrogen Sulfide gas sensors operate using well-known fuel cell technology.

Sensors are available in the following sizes:

A: 20mm diameter, the industry standard size for portable gas detectors

B: 32mm diameter package, the best choice for fixed site applications

D: miniature, with proven long-term performance. Sensors for the next generation of portable gas detectors

With very high sensitivity and low zero, accurate and stable readings are possible when measuring current concentration ranges from ppb to 1% H2S.

See application note AAN-105 for circuit design tips.
