The Kestrel 2500 Weather Meter provides high quality, performance and functionality. It has three buttons below the display, making operation simple and allowing the user to view data in current, maximum and average wind speed displays, temperature, barometric pressure, altitude and wind chill displays and also the data hold function.
Wind chill is an equivalent temperature that indicates to the user how their environment really feels. Wind chill is the combination of wind speed and temperature.
The Kestrel 2500 is a small, electronic rotating vane type anemometer (wind meter) with built-in temperature and pressure sensors. It uses high precision Zytel® bearings and a lightweight impeller to provide accurate air flow measurements even at low speeds. The impeller assembly is replaceable by the user in the case of damage.
In order to quickly determine a steady temperature reading, the precision thermistor temperature sensor is mounted externally. A monolithic silicon based pressure sensor enables barometric pressure and altitude to be calculated, with a resolution of 0.1hPa and 1m respectively.
The liquid crystal display has large 9mm high digits and is backlit for a clear readout in low light conditions. Power is from an easily replaceable standard lithium coin cell battery, which will typically give up to 300 hours of operation. The instrument automatically switches off if no keys are pressed for 45 minutes.
For those with requirements to operate in the dark, the Kestrel 2500NV (with an olive drab case) is available with a low intensity red backlight to preserve night vision. Click here for more information »
The Kestrel 2500 Weather Meter is made from high impact injection moulded plastic and corrosion resistant materials with the electronics fully sealed. It will float if accidentally dropped into water. There is a hard cover for protection when not in use and a lanyard for added security.
