Vane Thermo-Anemometer Test Instrument

The Dwyer 473B-1 100 mm Vane Thermo-Anemometer Test Instrument is a versatile unit that quickly and easily measures air velocity or volumetric airflow, as well as air temperature and humidity in imperial or metric units. A stainless steel 100 mm vane probe is included, which has a comfortable handgrip. The extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold.

The 473-B is also compatible with two other probes - the AP1 thermo-anemometer probe, and RP1 thermo-hygrometer probe. Both are sold separately.
