Model 471B Thermo-Anemometer Test Instrument

Brand: Dwyer Instruments, LLC
Does not ship to United States
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.
Features
  • Compatible with Dwyer RP1 thermo-hygrometer and VP1 100 mm vane thermo-anemometer probes (sold separately)
  • High contrast and backlit LCD for visibility in any condition
  • Able to store up to 99 readings
  • Integral sliding cover protects probe sensors when not in use
  • Built-in volumetric air flow calculations
