Carbon Dioxide Detection Tubes 1%/a (1 - 20 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 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 20 Vol. %
Number of Strokes (n): 1
Time for Measurement: approx. 30 sec.
Standard Deviation: ±5 to 10 %
Color Change: white to violet
Temperature: max. 40° C
Absolute Humidity: max. 40 mg H2O / L
Reaction Principle: CO2 + N2H4 ─> NH2-NH-COOH
Cross Sensitivity: Hydrogen sulfide in the TLV range does not interfere. In a range comparable to the calibrated range for carbon dioxide, sulfur dioxide is indicated. The sulfur dioxide sensitivity is approximately 1/3 (e.g. 6 Vol.% sulfur dioxide gives an indication of 2 Vol.%)
