Airflow Instruments Multi-Function Anemometers

Multi-function anemometers streamline HVAC diagnostics by consolidating the most-used measurements into a single instrument. With Airflow Instruments, you can move from a diffuser to a fume hood to a return grille while maintaining consistent data and clear documentation.

Measurement Capabilities

• Velocity and Volume: Hot-wire probes excel at low flows and tight spaces; vane probes offer robust averaging at grilles and intakes.
• Temperature and Humidity: Capture comfort conditions and process constraints in the same workflow.
• Optional CO2: Screen ventilation effectiveness and demand-control sequences.
• Computed Flow: Enter area or duct dimensions to compute volumetric flow directly on the instrument.

Field Advantages

• Telescoping Probes: Reach deeper into ducts and across large face areas.
• Fast Response, Clear Display: See stable readings that support confident decision-making.
• Data Logging and Wireless Export: Tag locations, add notes, and export files for reports.

Use Cases

• Commissioning: Validate design velocities and volumes at critical terminals.
• Troubleshooting: Diagnose low airflow, stratification, and humidity-related comfort complaints.
• IAQ Checks: Pair velocity/volume with temperature, humidity, and CO2 indicators.
• Fume Hoods and Specialized Spaces: Verify sash performance and face velocity targets.

Tips for Best Results

• Probe Positioning: Maintain proper alignment with flow; use grids for large faces.
• Averaging: Take multiple points and average for repeatable data.
• Density Corrections: Apply when required by your reporting standard.
• Calibration: Keep probes clean and within calibration intervals to support stability.

Selection Considerations

• Probe Type: Choose hot-wire for low-flow sensitivity and tight spaces; vane for robust, quick measurements at higher flows.
• Range and Resolution: Match expected conditions for your typical projects.
• Workflow Tools: Consider Bluetooth, app integration, and logging capacity for larger jobs.

Combining versatility with reliable performance, these instruments help TAB professionals reduce tool changes and deliver comprehensive, well-documented results.
