Product Overview
The Dwyer Model 480 is designed for measuring low air velocities where a general-purpose anemometer may not provide the appropriate measurement range. It measures air velocity from 25 to 400 FPM, approximately 0.13 to 2.0 m/s, with a stated accuracy of ±5%.
The Model 480 combines a rotating vane and thermistor sensor in one instrument. This configuration is suited to applications where relatively gentle airflow needs to be checked, including laminar flow hood testing and clean-room airflow verification.
For controlled environments, airflow measurements are often taken at multiple points rather than at a single location. The Model 480 can be positioned in the low-velocity air stream and the reading taken within its 25-400 FPM measurement range. Measurements can then be repeated across different points of a hood face or room as part of an airflow verification procedure.
The instrument is purpose-built for low-FPM measurement, making its range distinct from higher-velocity HVAC airflow meters. It is particularly relevant where airflow conditions are below the typical range of standard duct anemometers.
For clean-room technicians, laminar flow hood testing teams, HVAC service personnel and facility teams working with controlled airflow environments, the Model 480 provides a dedicated low-velocity measurement option.
For higher airflow measurements up to 4,000 FPM, the Dwyer Model 460 provides two overlapping mechanical ranges from 260 to 1,200 FPM and 1,000 to 4,000 FPM.
