Product Description H2S-B4 Hydrogen Sulfide Sensor (H2S Sensor) DescriptionAlphasense 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 detectorsB: 32mm diameter package, the best choice for fixed site applicationsD: miniature, with proven long-term performance. Sensors for the next generation of portable gas detectorsWith very high sensitivity and low zero, accurate and stable readings are possible when measuring current concentration ranges from ppb to 1% H2S.

This potentiostat provides a dual channel voltage output.A low noise bandgap provides the bias voltage for NO sensors and the ISB can measure both oxidising (CO, H2S, SO2 and NO) and reducing (O3 and NO2) gases.The ISB is configured for specific sensors: NO, NO2, O3 and CO / H2S / SO2 .Designed for low power applications, the ISB requires 3.5 to 6.4 stable DC supply at only 1mA.
