Dwyer Instruments' Model 8901 Vane Thermo-Anemometer balances air conditioning and heating ducts
Dwyer Instruments' Model 8901 Vane Thermo-Anemometer is designed for balancing air conditioning and heating ducts or checking the operation of fans and blowers. Model 8901 measures air volume in cubic feet per minute and cubic centimeters per second, as well as air velocity in ft/min, m/s, knots, km/hr and mph with ±2% accuracy. The LCD is designed to simultaneously display air velocity and temperature, or air flow and temperature, in selectable units. A built-in temperature sensor is engineered to provide measurements with an accuracy of ±2 with the capability to display the results in ° F/° C. Model 8901 can either store measurements or transfer the data to a PC via RS-232 communication. Additional features include data hold, as well as the ability to record minimum, maximum and average readings.
