Airflow™ Instruments

Airflow Instruments are engineered to support the full workflow of HVAC test and balance, from design verification to seasonal re-commissioning. Whether you are validating a VAV system, troubleshooting comfort complaints, or documenting ventilation rates, you gain a cohesive toolkit that helps you work accurately and efficiently.

Key Categories and Use Cases

• Capture Hoods (Balometers): Quickly determine supply and return airflow at diffusers and grilles. Interchangeable hood sizes support large open areas and tight plenums. Backpressure-compensating designs help you get stable volumetric readings without complex setup.
• Micromanometers: High-resolution differential pressure readings help diagnose duct pressure profiles, measure pitot tube velocity, and confirm setpoints at air handlers and VAV boxes.
• Multi-Function Anemometers: Measure air velocity, temperature, humidity, and often CO2 with interchangeable or telescoping probes to cover supply outlets, fume hoods, and clean areas.
• Rotating Vane Anemometers: Robust tools for average face velocity and grille measurements that are fast to deploy and simple to read.
• Duct Leakage Testers: Pressurize duct sections and log leakage at a target class or pressure to support commissioning, code requirements, and energy performance goals.

Why It Matters for TAB

• Speed and Repeatability: Purpose-built instruments reduce setup time and help produce repeatable results between technicians.
• Data Confidence: Stable sensors and logical workflows help reduce rework and call-backs.
• Reporting Efficiency: Many instruments pair with apps or software to tag locations, capture notes, and generate reports that align with client requirements.

Selection Tips

• Scope: Choose capture hoods for volumetric airflow at terminals; choose micromanometers and pitot tubes for duct velocity/pressure; choose multi-function anemometers for mixed troubleshooting and IAQ checks.
• Range and Resolution: Match expected flow/pressure ranges to sensor capability for reliable readings on both low- and high-flow systems.
• Data Workflow: Consider onboard logging, Bluetooth connectivity, and format options that integrate with your firm’s reports.

Best Practices

• Stabilize measurement positions and follow standardized traverse procedures.
• Account for temperature and barometric pressure when required.
• Verify calibration status and keep field standards to help validate performance between annual calibrations.

Airflow Instruments help you deliver clear, consistent measurements and clean documentation — key to high-performing HVAC systems and satisfied clients.
