Vane Thermo-Anemometer

Measures Air Volume, Air Velocity, and Temperature

Model 8901 Vane Thermo-Anemometer is ideal 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 multifunction LCD can simultaneously display
air velocity and temperature or air flow and temperature in selectable units. Built-in
temperature sensor provides 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. These units also feature a detachable probe
for easy replacement, if necessary. Model 8901 includes battery, carrying case and instruction
manual.
