Draeger 8101721 Vinyl Chloride 0.5/b Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 5 to 30 ppm / 0.5 to 5 ppm
• Number of Strokes n: 1 / 5
• Time for Measurement: approx. 30 s / approx. 2.5 min
• Standard Deviation: ± 15 to 20 %
• Color Change: white → violet

Ambient Operating Conditions:

• Temperature: 10 to 30 °C
• Absolute Humidity: max. 20 mg H2O / L

Reaction Principle:

• a) CH2=CHCI + CrVI ä Cl2
• b) Cl2 + dimethyl naphtidine → violet reaction product

Cross Sensitivity:

• 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
