Draeger CH25101 Carbon Dioxide 1%/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 1 to 20 vol. %
• Number of Strokes n: 1
• Time for Measurement: Approx. 30 sec
• 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. %).
