Application Range:

• Standard Measuring Range: 20 to 200 ppm
• Number of Strokes n: 8
• Time for Measurement: approx. 7 min.
• Standard Deviation: ± 15 to 25 %
• Color Change: Yellow → Red

Ambient Operating Conditions:

• Temperature: 17 to 30 °C At 25 °C to 30 °C/77 °F to 86 °F multiply the reading with the factor 0.6.

Reaction Principle:

• a) CH2CI2 + chromate → CI2
• b) CI2 + amine → red reaction product

Cross Sensitivity:

• 100 ppm n-octane and 300 ppm carbon monoxide do not interfere the reading.
• In case of concentrations > 100 ppm n-octane, methylene chloride is not indicated.
• Other chlorinated hydrocarbons will be indicated.
