AlphaSense H2S-A1 Hydrogen Sulfide Sensor

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 and also is compatible with the EC board. Note: Once an electrochemical (EC) sensor is purchased from Gaslab.com and the sealed packaging is opened or the sensor module is installed, it is no longer eligible for return due to the limited operational lifespan that begins upon activation. 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 fr
