MSA XCell Replacement SO2/H2S Sensor - 10121215MSA XCell Sensors are a breakthrough in sensor design, enabling faster response and shorter span calibrations, saving you time and money. ASIC (application-specific integrated circuit) technology inside of each sensor provides greater control and higher performance than other sensors on the market. Every XCell Sensor is built by MSA with a proprietary embedded ASIC microchip that drives the sensor and converts its output to a digital signal. This microchip is much more than a digital sensor; XCell Sensors perform real-time environmental corrections, provide plug-and-play capabilities and deliver greater RF immunity with higher overall performance. MSA XCell Sensors have a typical life of more than four years*, double the industry average. By miniaturizing sensor controlling electronics and placing them inside of the sensor itself, MSA XCell Sensors offer superior response time, stability, accuracy, and reliability. MSA is proud to offer XCell Sensors with: State-of-the-art automated assembly for greater control and reliability. Laser-welded sensor housings to eliminate opportunities for leaks. End-of-sensor-life warning to minimize downtime and inventory replacement. H2S/SO2 Sensor P/N 10121215 Gas: Sulfur dioxide/Hydrogen Sulfide Package: Two-Tox Range: 0-20 ppm SO2 Resolution: 0.1 ppm SO2 Response Time (typ): t(90) 4-year life outlasts competition by more than 33%. Response: industry-leading response time not only helps to save lives, but your time and money as well. Resilience: XCell Sensors continues to perform within low humidity environments when others do not.
