The Kestrel 4500 handheld meteorological instrument is a fully functional portable meteorological instrument that can measure wind direction, crosswind, headwind/tailwind, altitude, atmospheric pressure trend, atmospheric pressure, wet bulb temperature, relative humidity, thermal stress index, dew point, wet bulb temperature, altitude density, wind chill, air, water and snow temperature ℉ or ℃, current, average, and maximum airflow velocity. It can store 2900 sets of data and view the maximum, minimum, and average values, making field meteorological data collection more convenient. There are also NV models available for users to choose from. The NV model's screen background light has night vision function, which users can use at night.
