This handy wing wheel anemometer measures air speeds in meters per second, kilometers per hour, feet per minute, knots, and miles per hour, as well as the current air temperature. It displays two measurements simultaneously. The multi-line LCD display features an automatic backlight that activates itself in low light conditions via a photodiode. On the side, there are buttons for Data Hold, MAX, AVG, or measurement function selection. This compact and affordable device is particularly suitable for educational purposes or outdoor use.
