Check out these winds! This young man used our Extech Large Vane Thermo-Anemometer to capture gusts blowing at 38 mph in South Wales. If you're not into high velocity winds, our Extech AN300 works perfectly fine for routine HVAC inspections too 😉 https://bit.ly/3IB32YG | Teledyne FLIR

Wind speed is typically measured using an anemometer, with common types including the cup anemometer, vane anemometer, hot-wire anemometer, ultrasonic anemometer, and Pitot tube. These instruments work by detecting the movement of air, either through mechanical rotation, changes in electrical resistance, sound wave travel times, or pressure differences. Wind speed is usually expressed in meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), or knots. #windspeed #wind #scienc
