Application Range
Standard Measuring Range: 0.5 to 10 vol. %
Number of Strokes (n): 1
Time for Measurement: approx. 30 s
Standard Deviation: ±5 to 10%
Color Change: white -› violet
Ambient Operating Conditions
Temperature: 0 to 40°C
Absolute Humidity: max. 50 mg H2O / L
Reaction Principle
CO2 + Amine -> violet reaction product
Cross Sensitivity
Hydrogen sulfide in the TLV range does not interfere. In a range comparable to the calibrated range for carbon dioxide, sulfur dioxide is indicated. The sulfur dioxide sensitivity is approximately
1/3 (e.g. 3 vol. % sulfur dioxide gives an indication of 1 vol. %).
