MSA announces the SO2/H2S-LC XCell Sensor for ALTAIR 4X Multigas Detectors. Ideal for monitoring sulfur dioxide in a compact personal gas monitor, new SO2/H2S-LC XCell Sensor provides detection ranges of 0-20 ppm SO2 and 0-100 ppm H2S with 0.1 ppm resolution on both channels. Standard H2S low concentration channel meets ACGIH recommendations for 1 ppm TLV. Sensor’s fast t(90) <15 seconds response times provide bump tests in less than 10 seconds, full span calibration in 60 seconds.
