Draeger 8101521 Phosgene 0.02/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 0.02 to 1 ppm / 0.02 to 0.6 ppm
• Number of Strokes n: 20 / 40
• Time for Measurement: approx. 6 min / approx. 12 min
• Standard Deviation: ± 10 to 15 %
• Color Change: white → red

Ambient Operating Conditions:

• Temperature: 0 to 40 °C
• Absolute Humidity: 3 to 15 mg H2O / L

Reaction Principle:

• COCI2 + aromatic amine → red reaction product

Cross Sensitivity:

• Chlorine and hydrochloric acid lead to plus errors and, at higher concentrations, to bleaching of the indicating layer.
• Concentrations of phosgene above 30 ppm will also lead to bleaching of the indicating layer.

Additional Information:

• High concentrations of phosgene will be not indicated.
