Description
The swinging-plate anemometer was one of the earliest devices invented to measure wind speed. The instrument is set up facing into the wind and the plate swings against the arc which is graduated in degrees, giving a rough measure of the wind strength.

Joseph Dickinson devised this portable anemometer in 1854 for testing ventilation in mine tunnels and shafts. This example was made by Casartelli of Manchester.
