    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.

    Product Applications

    • Duct traverses
    • HVAC inspections
    • Testing and balancing
