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, 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:
||5 to 30 ppm / 0.5 to 5 ppm
|Number of Strokes (n):
||1 / 5
|Time for Measurement:
||approx. 30 sec / approx. 2.5 min
||±15 to 20 %
||white ──> violet
||10 to 30° C
||max. 20 mg H2O / L
||a) Ch2=CHCl + CrVI ──> Cl2
b) Cl2 + dimethyl naphtidine ──> violet reaction product
||100 ppm hydrogen chloride, 20 ppm chlorine, 10 ppm carbon tetrachloride, 10 ppm chloroform or 5 ppm perchloroethylene are not indicated.
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 ethylene
