The Model

471B Thermo-Anemometer Test Instrument is a versatile dual function

unit that quickly and easily measures air velocity or volumetric ow 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/BENEFITS

• 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 ow calculations

APPLICATIONS

• Duct traverses

• HVAC inspections

• Testing and balancing
