MSA has introduced the CO/NO2 XCell Sensor for ALTAIR 4X Multigas Detectors. This sensor is ideal for monitoring for diesel emissions. The new CO/NO2 XCell Sensor provides a range of 0-2000 ppm CO and 0-50 ppm NO2, 1 ppm and 0.1 ppm resolution respectively. Sensor’s fast response time allows users to bump test in less than 10 seconds and perform full span calibration in 60 seconds. MSA,, (800) 672-2222. Circle 262MSA_300px.jpg
