Alnor ABT Balometer Capture Hoods

The Alnor ABT Balometer capture hood series is designed for direct volumetric airflow measurement at diffusers and grilles — ideal for research labs, test mockups, and on-site validation. By capturing the full face of the outlet, ABT hoods help reduce the need for multi-point velocity averaging, simplifying studies where time, repeatability, and clear documentation are critical.

ABT Balometers are built around a stable, low-leakage frame and interchangeable hood sizes, making it straightforward to adapt to various diffuser geometries and air distribution strategies. The integrated micromanometer provides clear, immediate readings with options for data logging and export, supporting test plans that require traceable, repeatable results.

Why ABT for research and development:

• Direct volume measurement at the source supports diffuser characterization, balance checks, and system benchmarking.
• Quick-change hoods reduce setup time across test conditions, improving throughput for experimental campaigns.
• Portable designs enable rapid deployment across labs, mockups, and occupied spaces without special tooling.
• Data capture capabilities integrate with analysis workflows for reporting and peer review.
• Calibration services support QA/QC programs and consistent measurements over time.

Use cases include:

• Evaluating diffuser performance under varying flow and pressure conditions.
• Validating VAV control sequences and measuring turn-down performance.
• Measuring room airflow supply and return to support air-change studies.
• Comparing air distribution strategies for comfort and energy outcomes.
• Teaching laboratories and training environments where students need hands-on exposure to airflow measurement.

ABT Balometer hoods help researchers move from concept to data quickly. When combined with micromanometers, vanes, and thermal anemometers, they form a versatile toolkit for comprehensive ventilation research.
