Carbon Dioxide Detection Tubes 1%/a (1 - 20 Vol.%)
For short-term measurements more than 160 Draeger-Tubes are available to measure the spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
A wide range of different gases and vapours can be detected and measured, such as:

|
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.%) |
