Determine Air Velocity and Temperature Levels in Ducts or Air Supply Grills

The Series 471B Digital Thermo-Anemometer is the ideal portable product for determining air velocity and temperature levels in ducts or air supply grills. The 471B is a versatile dual function unit that quickly measures air velocity, volumetric flow, and air temperature in imperial or metric units. It can measure from 0 to 6000 FPM (0 to 20 m/s) for air velocity, 19,999 in selected flow units for volumetric air flow, and -40 to 212°F (-40 to 100°C) for temperature. A stainless steel probe is included, which has a comfortable hand grip and etched insertion depth marks. The extruded aluminum housing fully protects the electronics, yet is lightweight and comfortable to hold.
