For short-term measurements more than 160 Dräger-Tubes are available to measure the so-called spot concentrations of specific gases. A wide range of different gases and vapours can be detected and measured, e.g.: determining and measuring concentration peaks, measuring personal exposure in the inhalation area, detecting leaks in pipelines, gas installations etc., and air analysis in sewers, shafts and confined spaces.Arsine 1/a, Standard range (20° C, 1013 hPa): - 0.05-3 ppm (measurement time approx 6 minutes)
