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
Standard Measuring Range: 1 to 25 ppm
Number of strokes n: 10
Time for Measurement: approx. 3 min
Standard Deviation: ± 10 to 15 %
Color Change: gray blue──> white
Temperature: 15 to 25 °C
Absolute Humidity: 3 to 20 mg H2O / L
Reaction Principle: SO2 + I2 + 2 H2O ──> H2SO4 + 2 HI
Cross Sensitivity: Hydrogen sulfide in the TLV range is retained in the pre-layer and does not interfere. Nitrogen dioxide will shorten the reading.
