Ozone Detection Tubes 0.05/b (0.05 - 1.4 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.

1 ppm sulfur dioxide
1 ppm chlorine
1 ppm nitrogen dioxide
Higher concentrations of chlorine and
nitrogen dioxide discolor the indicating
layer a diffuse white to pale gray.
|Extension of the Measuring|
|Using n=5, multiply the reading by 2;|
the measuring range will be 0.1 to 1.4 ppm.
Using n=100, divide the reading by 10;
the range of measurement is 0.005 to 0.07ppm.
