    Model 473B 100 mm Vane Thermo-Anemometer Test Instrument

    Measures Air Velocity or Air Volume, Temperature, and Humidity Simultaneously

    The MODEL 473B 100 mm Vane Thermo-Anemometer Test Instrument is a versatile unit that quickly and easily measures air velocity or volumetric air flow, as well as air temperature and humidity in imperial or metric units. A stainless steel 100 mm vane probe is included, which has a comfortable hand grip. The extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold.

    Product Applications

    • Residential balancing
    • HVAC inspections
