Hydrogen Sulfide Detection Tubes 2/b (1 - 60 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 vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
|Standard Measuring Range:
||2 to 60 ppm
|Number of strokes n:
|Time for Measurement:
||approx. 30 sec
||± 5 to 10 %
||white ──> pale brown
||0 to 40°C
