Carbon Dioxide 0.5 %/a, 0.5 - 10 Vol.-%, Part # CH31401, 10 Tests 

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 š violet

Ambient Operating Conditions

Temperature: 0 to 40 °C

Absolute Humidity: max. 50 mg H2O / L

Reaction Principle

CO2 + amine š   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. %).
