Vinyl Chloride Detection Tubes 0.5/b (0.5 - 30 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, 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 20 ppm / 0.5 to 5 ppm |
|Number of Strokes (n)||1 / 5|
|Time for Measurement||approx. 30 sec. / approx. 3 min.|
|Standard Deviation|| ±15 to 20 %|
|Colour Change||white ──> violet|
|Temperature||10 to 30° C|
|Absolute Humidity||max. 20 mg H2O / L|
|Reaction Humidity||a) Ch2=CHCl + Cr^VI ──> Cl2|
b) Cl2 + dimethyl naphthalene ──> violet
|Cross Sensitivity||100 ppm hydrogen chloride, 20 ppm chlorine,|
10 ppm carbon tetrachloride, 10 ppm
chloroform or 5 ppm perchloroethylene are
Trichloroethylene and chlorobenzene are
indicated with less sensitivity.
1.1-dichloroethylene is indicated with almost
identical sensitivity. Vapors of organic solvents
consume part of the oxidation layer so that the
resultant reading is somewhat lower.
Examples: a reading of 0.5 ppm vinyl chloride
will occur by 5 ppm vinyl chloride + 100 ppm
butadiene or 5 ppm vinyl chloride + 10 ppm
