Dwyer Instruments 480 Vaneometer

The Dwyer Instruments 480 Vaneometer is a specialized swing vane anemometer engineered for technicians who need to verify low air velocities in critical environments. Designed to provide high-accuracy readings in the 25 to 400 FPM range, this low air velocity meter is the industry standard for checking compliance at spray booths, laboratory fume hoods, and dust exhaust systems. Its portable air flow measurement capability makes it a staple for onsite safety inspections where meeting OSHA and EPA ventilation standards is mandatory.

Constructed with a durable ABS plastic housing, the Model 480 is built to withstand the rigors of field use while weighing only four ounces. It features an integrated spirit level to ensure the instrument is perfectly horizontal for the highest precision. Accuracy is rated at ±5% of full scale up to 100 FPM and ±10% from 100 FPM to the top of the scale. The large, high-visibility scales are readable from both sides, allowing for flexible positioning in tight ductwork or hood openings. For permanent monitoring, a versatile steel mounting bracket is included, and the polyester vane is resistant to common cleaning agents like lacquer thinner.

• OSHA Compliance: Quickly verify minimum face velocity requirements for fume hoods and paint booths to ensure operator safety.
• High Sensitivity: Optimized for detecting subtle air movement that standard digital anemometers often miss.
• Field Reliability: Simple mechanical design requires no batteries, ensuring the tool is always ready for immediate HVAC air velocity testing.
• Easy Maintenance: The ABS plastic housing and polyester vane are easily cleaned, maintaining visibility and accuracy over time.

• How do I ensure the most accurate reading? Always use the built-in spirit level to ensure the unit is level; even a slight tilt can affect the swing vane's gravity-based measurement.
• Can this be used for continuous monitoring? Yes, the included steel bracket allows you to mount the 480 permanently for ongoing airflow verification.
• What happens if the vane gets damaged? The unit is supplied with a spare vane, and the polyester material is designed for durability against chemical vapors.
