Hydrochloric Acid Detection Tubes 50/a (50 - 5000 ppm)
For short-term measurements more than 160 Draeger-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.
