    Dräger Safety offer a massive range of short-term gas detection tubes for the measurement of various gases. This particular set of tubes is for (Carbon Monoxide 5/a-P).

    The tubes come in a pack of 1 tubes and have a shelf life of 2 years.

    Application Range:

    Use in Aerotest 5000, Aerotest Alpha, MultiTest med. Int., Aerotest Silmultaneous HP, Simultantest CO2

    Standard Measuring Range: 5 to 150 ppm
    Test Volume: 1L
    Flow Rate: 0.2 L / min
    Time for Measurement: approx. 5 min
    Standard Deviation: ± 10 to 15 %
    Colour Change: white to brwnish-green

    Ambient Operating Conditions:

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

    Reaction Principle:

    5 CO + I2O5 ~ H2S2O7 ~> 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.

    Evaluation:

    Using a test volume of 2 L divide the reading by 2, measuring range 2.5 to 75 ppm..
