Oxygen Detection Tubes 5%C (5 - 23 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, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.
Contains 10 tubes
|Standard Measuring Range||5 to 23 Vol.-%|
|Number of strokes n:||1|
|Time for Measurement||approx. 1 min.|
|Standard Deviation||± 10 to 15 %|
|Color Change||blue black ──> white|
|Temperature||5 to 50 °C|
|Absolute Humidity||0 to 40 mg H2O / L|
|Reaction Principle||a) O2 + TiCl3 ──> Ti^IV compound|
b) Adsorption of the hydrochloric acid,
generated during reaction, by a silica
gel filter layer.
|Cross Sensitivity||Carbon dioxide, carbon monoxide, |
solvent vapors, halogenated hydrocarbons
and N2O do not affect the indication.
|Additional Information||These tubes become very warm during|
measurement, reaching temperature of
approx. 100°C. Therefore these tubes
should not be used in potentially combustible
atmospheres. If in doubt, test the area
before using the tube with a combustible
gas monitor, before using the tube.
