Alnor ABT Balometer Capture Hoods

Balancing airflow across a life science facility is critical for maintaining directional flow, dilution, and pressure relationships. The Alnor ABT Balometer Capture Hood is designed for the job — delivering direct volumetric flow measurements at supply and return terminals to speed up testing, adjusting, and balancing (TAB).

Purpose-Built for Field Efficiency

• Interchangeable hoods adapt to a wide range of diffuser styles and sizes, reducing the need for multiple instruments.
• A lightweight frame and ergonomic handles help technicians move quickly, minimizing fatigue across large projects.
• A bright, easy-to-read display supports measurements in varied lighting, including ceiling plenums and corridors.

Integrated Measurement Capability

• The detachable micromanometer enables additional diagnostics, such as pressure checks and pitot traverses, without changing tools.
• Flow averaging and stabilization help produce repeatable results, even with moderate turbulence at terminals.
• Data logging and export options streamline reporting, enabling consistent documentation and trend analysis.

Life Science Use Cases

• Commission ISO-classified suites by measuring each supply and return point, balancing zones to support pressure cascading strategies.
• Verify ACH targets indirectly by measuring terminal flows and relating them to room volume and occupancy.
• Resolve hot/cold complaints and variability in containment performance by identifying underperforming diffusers or returns.
• Support pharmacy cleanroom validation by documenting terminal flows alongside differential pressure and particle readings.

Best Practices

• Select the hood size that fully captures the diffuser footprint for representative readings.
• Center the hood and maintain a proper seal around the diffuser to reduce bypass leakage.
• Allow readings to stabilize and repeat measurements to assess consistency.
• Record location, diffuser type, and hood size with each reading to simplify reporting and future comparisons.

Calibration and Traceability

• Routine calibration supports dependable performance across projects and technicians. Certificates with traceable references help align with quality system expectations.

With robust build quality and practical features, Alnor ABT Balometer Capture Hoods help TAB professionals and facility teams move from measurement to action — balancing systems efficiently and producing the documentation needed to support compliance objectives in labs, cleanrooms, and healthcare environments.
