Digital Thermo-Anemometer Test Instrument
The Dwyer 471B-1 Thermo-Anemometer Test Instrument is a versatile dual function unit that quickly and easily measures air velocity or volumetric flow as well as air temperature in imperial or metric units. A stainless steel probe is included, which has a comfortable hand grip and etched insertion depth marks. The extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold.
The 471B-1 is also compatible with two other probes - the VP1 vane thermo-anemometer probe, and RP1 thermo-hygrometer probe. Both are sold separately.
