Ideal for larger air supplies and returns, this capture hood enables fast and precise testing and balancing of indoor environmental systems. Additionally, it provides reliable data with precise calculations of the overall volume flow in HVAC/R systems.
Features
Exceptionally light
This air flow capture hood with ergonomic handles and tilt-able display has an exceptional light weight of less than 6.4 lbs. This means that frequent volume flow calculations in large rooms and measurements above head height can be carried out reliably and comfortably. While in use, a large measuring button on the capture hood ensures easy recording of the measurements.
Removable control unit
The control unit of this capture hood enables you to measure flow velocity, volume flow, absolute pressure, temperature, and relative humidity. The automatic zeroing ensures higher accuracy for low pressures. This integrated measuring control unit was not just developed for volume flow measurement at ceiling outlets, as it can be removed from the capture hood and be used for pressure, flow, and volume flow measurements in the duct. You only need to attach a pitot tube and connection hoses (sold separately) for measurements in ducts. Timed and multi-point mean calculation, as well as the combination of the two, together with simple input of the duct geometry, provide you with accurate flow measurements in ducts.
