M480 Swing Vane Anemometer, 0 to 2.0 m/s. Accurately Measure Slow-Moving Air Currents in Spray Booths and Fume Hoods. No Power Required. Mounting Bracket Included.

Description

Product Overview

The Dwyer M480 Swing Vane Anemometer is engineered for reliable measurement of slow‑moving air currents in industrial and laboratory environments. Constructed from molded ABS plastic, the housing resists chemicals, is easy to clean with soap and water, and endures the rigors of daily use. The polyester vane can be refreshed with lacquer thinner, and a spare vane is supplied for added convenience. Integrated spirit levels guarantee accurate alignment, while the large dual‑sided scales provide clear visibility from any angle. The device measures velocities from 0 to 2.0 m/s, delivering accuracy of ±5 % of full scale up to 0.5 m/s and ±10 % beyond that range. Dimensions of 3.8 × 1.6 × 3.9 inches and a weight of only 4 oz make it exceptionally portable, and the included steel mounting bracket enables permanent installation for continuous monitoring.

Usage

Designed for spray booths, fume hoods, clean rooms, and other controlled environments, the M480 helps technicians verify airflow rates to meet safety and regulatory standards. Its zero‑power operation means it can be placed in locations without access to electricity, making it ideal for temporary setups or field inspections. Users can quickly attach the device to a workbench, handheld stand, or the supplied mounting bracket to monitor air velocity during filter changes, equipment maintenance, or routine safety checks. The lightweight form factor allows technicians to move the instrument between stations, ensuring consistent data collection across multiple work areas.

FAQ

What velocity range can the M480 measure?

The instrument accurately measures air velocities from 0 up to 2.0 m/s, covering the low‑speed range typical of spray booths and fume hoods.

Do I need batteries or an external power source?

No. The M480 operates entirely by the movement of air across the swing vane, so it requires no batteries or external power.

Can the device be mounted for continuous monitoring?

Yes. A sturdy steel mounting bracket is included, allowing the anemometer to be fixed in place for ongoing airflow observation.

How often should the vane be cleaned?

The polyester vane can be cleaned with lacquer thinner when contaminated. Regular cleaning ensures accurate readings and extends the life of the instrument.
