The thermo-anemometer AN500 Extech model is an instrument that measures the flow and read the air velocity and temperature by placing the sensor in a duct or a vent, showing the results on its dual screen. Calculate CMM / CFM based on the shape and size adjustment conduit.
The thin sensor (8 mm) fits easily into holes 8.3 "and telescopic probe extends 7 feet (2,1 m) for more accurate measurements, just as technology has CAT (automatic temperature compensation).
It also has the ability to save and view 36 readings on the screen, adjustable parameters for height, maximum and average minimum data hold, auto power off and universal adapter 100V-240V AC, with 4 plugs, 6 batteries, and a case hard.
The thermo-anemometer AN500 is designed with an ergonomic handle and an anti-rotation sensor that prevents the change in direction of the probe with air flow to remain always aligned.
