This isn't your basic wind meter - it's a full-featured professional anemometer that measures wind speed, temperature, AND humidity all in one handy device! It covers wind speeds from 0-45 m/s (that's about 100 mph) and can display in multiple units: m/s, km/h, ft/min, knots, or mph. The air flow measurement goes up to 999,900 CFM or CMM, plus it reads temperature from 32-113°F and humidity from 10-90% RH. But here's the cool part - it actually shows wind direction too (N, S, E, W, and all the diagonals) and stores up to 960 data sets for later analysis. The USB connectivity lets you download data to your computer, and there's even a tripod mount for hands-free operation. Perfect for drone pilots checking flight conditions, sailors monitoring weather, HVAC technicians measuring airflow, or anyone who needs accurate environmental measurements. It comes with a protective carrying case, auxiliary fan for testing, and runs on 4 AAA batteries. The auto power-off feature saves battery life, and the large display makes readings easy to see in various lighting conditions.
