Draeger 8101511 Hydrogen 0.2%/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 0.2 to 2.0 vol. %
• Number of Strokes n: 1
• Time for Measurement: Approx. 1 min
• Standard Deviation: ± 15 to 20 %
• Color Change: Green Yellow → Turquoise Blue

Ambient Operating Conditions:

• Temperature: 20 to 40 °C
• Absolute Humidity: max. 50 mg H2O / L

Reaction Principle:

• a) H2 + 1/2 O2 → H20
• b) H2O + indicator → turquoise blue reaction product

Cross Sensitivity:

• No interference by:
  • 0.1 vol. % acetylene
  • 6 vol. % alcohol
  • 6 vol. % ammonia
  • 0.5 vol. % carbon monoxide

Additional Information:

• The indicating layer is heated up by hydrogen concentrations of more than 10 vol. %.
• The air sample must not contain additional flammable substances whose ignition temperature is below 250 °C/ 482 °F as this will cause an explosion risk.
