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 functionunit that quickly and easily measures air velocity or volumetric flow as well as airtemperature in imperial or metric units. A stainless steel probe is included, which hasa comfortable hand grip and etched insertion depth marks. The extruded aluminumhousing fully protects electronics, yet is lightweight and comfortable to hold.

NIST CALIBRATION available in Product Configurator.
