Dwyer MODEL 471B THERMO-ANEMOMETER TEST INSTRUMENT

Description

Dwyer 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. NIST CALIBRATION available in Product Configurator.
