Carbon Dioxide 1 %/a, 1 - 20 Vol.-%, Part # CH25101, 10 Tests 

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 š violet

Ambient Operating Conditions

Temperature: 0 to 40 °C

Absolute Humidity: max. 40 mg H2O / L

Reaction Principle

CO2 + N2H4 š 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. %).
