About This Product
The Dwyer 471B measures air velocity from 0 to 6000 FPM (0-30 m/s) and temperature from -40 to 212 degrees F with a stainless steel probe featuring etched insertion depth marks. Accuracy of +/-3% FS for velocity and +/-0.5 degrees F for temperature. Stores up to 99 readings in an extruded aluminum housing. Ideal for duct traverses, HVAC inspections, and test-and-balance work.
