H2S-A1 Alphasense 1% Hydrogen Sulfide Sensor

The H2S-A1 AlphaSense Hydrogen Sulfide Sensor (formerly known as the AP-0006) 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 and also is compatible with the EC board. For Sensor Tube Caps, please look under the "Accessories" Tab 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 Specifications Measuring Gas: Hydrogen Sulfide Sensing Method: Fuel cell Sensivity (nA/ppm in 20ppm H2S): 550 to 875ppm Response time (t90 from zero to 20ppm H2S): < 35 sec. Zero Current (ppm equivalent in zero air) < ± 0.4ppm Resolution (RMS noise ppm equivalent): < 0.05ppm Range (H2S limit of performance warranty): 100ppm Linearity (ppm err
