Model 471B Thermo-Anemometer Test Instrument for Dry Air

model 471b thermo-anemometer test instrument

measures air velocity or air volume and temperature simultaneously

the model 471b 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.
