The EOi450 Flux chamber (a.k.a Emission Isolation Flux Hood) is used to determine levels of emissions from solid or liquid surfaces. The OEi450 has a 100% solid stainless steel construction to ensure zero cross contamination. Flotation is achieved using 4 stainless steel floats eliminating the need for rubber tubes or foam making the unit easy to clean and maintain.
The OEi450 is set up to enclose a surface area of 240 Sq Inches or 0.155 Sq meters in accordance to the EPA Recommendations. Odourless air (sweep air) is introduced to the chamber at a known flow rate (Recommended 3.875 LPM) to mix with the emissions. Sample is then drawn from the flux chamber at lower rate using a sampling device.
