Hydrogen Sulfide + Sulfur Dioxide Detection Tubes 0.2%/A (0.02 - 7% vol)
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:
||0.2 to 7 Vol. %
|Number of Strokes (n):
||1 + 2 desorption strokes in clean air
|Time for Measurement:
||approx. 2 min
||±5 to 10 %
||brown ─> pale yellow
||0 to 40° C
||max. 40 mg H2O / L
||H2S + I2 ──> 2 Hl + S2
SO2 + I2 + H2O ──> 2 Hl + H2SO4
||All substances oxidized by iodine are indicated, but with different sensitivities. It is impossible to measure hydrogen sulfide and sulfur dioxide in the presence of such substances.
|Extension of the Measuring
|Using n = 10, divide the reading by 10; the measuring range will be 0.02 to 0.7 vol. %
