Application Range
Standard Measuring Range: 1 to 20 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. 40 mg H2O / L
Reaction Principle
CO2 + N2H4 -> NH2-NH-COOH
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. 6 vol. % sulfur dioxide gives an indication of 2 vol. %)
