Product Description
H2S-D4 Hydrogen Sulfide Sensor (H2S Sensor) Description
Alphasense Hydrogen Sulfide gas sensors operate using well-known fuel cell technology.
H2S-D4 Hydrogen Sulfide Sensor size:
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.
