Carbon Monoxide Detection Tubes 2/a (2 - 300 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: 2 to 60 ppm / 25 to 300 ppm
Number of Strokes (n): 10 / 2
Time for Measurement: approx. 4 min. / 50 sec.
Standard Deviation: ±10 to 15 %
Color Change: white ─> brownish pink/green
Temperature: 0 to 50° C
Absolute Humidity: 2 to 20 mg H2O / L
Reaction Principle: 5 CO + I2O5 ─> I2 + 5 CO2
Cross Sensitivity: The following have no influence on the display of 10 ppm CO (respectively):
  • 100 ppm hydrogen sulphide
  • 50 ppm sulphur dioxide
  • 15 ppm nitrogen dioxide
  • 10 ppm CO + 200 ppm octane: display approx. 30 ppm
  • 10 ppm CO + 40 ppm butadiene: display approx. 15 ppm
  • 10 ppm CO + 30 (100) ppm benzene: display approx. 15 (20 - 30) ppm
  • 10 ppm CO + 40 ppm chloroform: display approx. 60 ppm
  • 10 (60) ppm acetylene: display approx. 5 (15) ppm
  • With the insertion of a carbon attachment tube (CH 24101), 10 ppm CO can still be measured in the presence of 10000 ppm n-octane
