Draeger 6728511 Carbon Monoxide 5/a-P Detector Tubes (10 tests per box)

Application Range:

• Use in Aerotest 5000, Aerotest Alpha, MultiTest med. Int., Aerotest HP, SimultanTest CO2
• Standard Measuring Range: 5 to 150 ppm
• Test Volume: 1 L
• Flow Rate: 0.2 L / min
• Time for Measurement: approx. 5 min
• Standard Deviation: ± 10 to 15 %
• Color Change: white → brownish-green

Ambient Operating Conditions:

• Temperature: 0 to 40 °C
• Absolute Humidity: max. 50 mg H2O / L
• Pressure: The tube may only be used for depressurized compressed air

Reaction Principle:

• H2S2O7 5 CO + I2O5 → I2 + 5 CO2

Cross Sensitivity:

• Acetylene reacts similarly to carbon monoxide but with less sensitivity.
• Petrol, benzene, halogenated hydrocarbons and hydrogen sulfide are retained in the pre-layer.
• Higher concentrations of easily cleavable halogenated hydrocarbons (e.g. trichloroethylene) may from chromyl chloride in the pre-layer which changes the indicating layer to yellowish-brown.
• In case of high olefine concentrations it is not possible to measure carbon monoxide.

Important Note: These tubes are only to be used with Draeger’s Aerotest Kits.
