Pittsburgh, Pa., April 2013 – MSA announces an industry-first 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 0.1ppm resolution on both channels. Standard H2S low concentration channel meets ACGIH recommendations for 1ppm TLV. Sensor’s fast t(90) <15 seconds response times provide bump tests in less than 10 seconds, full span calibration in 60 seconds. For more information, visit www.msasafety.com.
