Carbon Monoxide Detection Tubes 8/a (8 - 150 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: 8 to 150 ppm
Number of Strokes (n): 10
Time for Measurement: approx. 2 min.
Standard Deviation: ± 10 to 15 %
Color Change: white ─> pale brown
Temperature: 0 to 50° C
Absolute Humidity: < 50 mg H2O / L
Reaction Principle: 5 CO + I2O5 ─> I + 5 CO2
Cross Sensitivity Acetylene is also indicated, however, with less sensitivity. Petroleum hydrocarbons, benzene, halogenated hydrocarbons and hydrogen sulfide are retained in the pre-layer. In the case of higher concentrations of interfering hydrocarbons, use should be made of a carbon pre-tube (CH 24 101). Higher concentrations of easily cleavable halogenated hydrocarbons (e.g. trichloroethylene), are liable to form chromyl chloride in the pre-layer which changes the indicating layer to a yellowish-brown. CO determination is impossible in the case of high olefin concentrations.
