Product Description
Thermo-Anemometer Air Velocity & Temperature Instrument – Model 471B
The Model 471B Thermo-Anemometer Test Instrument is a versatile HVAC and industrial airflow diagnostic tool that simultaneously measures air velocity, volumetric air flow, and temperature in imperial or metric units. Built for duct traverses, system balancing, and commissioning work, this handheld meter includes a stainless steel probe with etched insertion marks and a rugged extruded-aluminum housing for long-term field use.
With onboard volumetric airflow calculations, storage for up to 99 readings, and a bright backlit 4.5-digit display, the 471B delivers dependable data collection for technicians working in mechanical rooms, rooftops, and plant environments.
