Sulfur Dioxide Detection Tubes 1/a (1 - 25 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, 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

||1 to 25 ppm
|Number of strokes n:
|Time for Measurement:
||approx. 3 min

||15 to 25 °C
||3 to 20 mg H2O / L

||Hydrogen sulfide in the TLV range is retained in the pre-layer and does not interfere. Nitrogen dioxide will shorten the reading.
