The Skywatch Atmost is a portable handheld unit measuring wind speed, temperature, wind chill (choice of units), relative humidity and dew point. It has multi-directional wind measuring cups which means that there is no need to point the unit directly into the wind.
The Atmos shows current, maximum and average wind speed. It also features a self-calibrating hygrometer with an accuracy of 3.5% and auto shut-off after 10 minutes.
