Alnor Capture Hoods

Alnor capture hoods help research teams quantify airflow at supply and return points with direct volumetric readings. Instead of relying on velocity traverses or assumptions about flow profiles, capture hoods enclose the diffuser face to collect the total flow, supporting reproducible measurements and faster test cycles.

Key capabilities for R&D environments:

• Interchangeable hood sizes accommodate a wide variety of diffuser and grille dimensions encountered in experiments and in situ measurements.
• Integrated displays support immediate feedback, while models with logging provide digital records and streamlined reporting.
• Lightweight designs enable one-person setup and efficient movement between test points — useful in time-constrained experiments.
• Accessories and stands support unique geometries and ceiling heights found in lab mockups and real buildings.

Where capture hoods add value:

• Room-level ventilation studies, including air-change benchmarking and space classification.
• Diffuser characterization under varying upstream conditions and flow regimes.
• Commissioning research where design intent is compared with measured performance.
• Education and training where hands-on, repeatable techniques are essential.

For comprehensive programs, pair capture hoods with micromanometers, rotating vanes, and thermal anemometers to build a robust measurement framework. This combination supports method comparisons, uncertainty analysis, and cross-validation between volume and velocity-based techniques — an important capability for publishable research and rigorous internal reviews.
