Vinyl Chloride 0.5/b, 5 - 30 PPM / 0.5 - 5 PPM, Part # 8101721, 10 Tests

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 š violet

Ambient Operating Conditions

Temperature: 10 to 30 °C

Absolute Humidity: max. 20 mg H2O / L

Reaction Principle

a) CH2=CHCI + CrVI š Cl2

b) Cl2 + dimethyl naphtidine š 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
