The Dwyer 480 Vaneometer Swing Vane Anemometer is a rugged, cost-effective instrument engineered to simplify low-air velocity measurements. Designed for precision and durability, it offers ±5% full-scale accuracy up to 100 FPM and ±10% accuracy from 100 FPM to its maximum range.

Equipped with a spirit level for alignment and large dual-sided scales for easy readability, the Model M480 is ideal for HVAC diagnostics, ventilation system checks, and other applications requiring reliable low-velocity airflow measurement.

• Accurate Low-Velocity Sensing: Measures air velocities with ±5% accuracy up to 100 FPM and ±10% accuracy beyond, suitable for precise low-flow applications.
• Dual-Sided Readability: Large scales visible from both sides enable quick, error-free readings in tight or hard-to-reach spaces.
• Spirit Level for Calibration: Integrated bubble level ensures proper instrument alignment for accurate measurements.
