Kestrel 4250 handheld anemometer

Kestrel 4250 is a handheld anemometer specifically designed for race tracks, allowing you to obtain accurate meteorological data at any time on the race track. It can measure air density, relative air density (RAD), local air pressure, moisture content (humidity ratio), and density altitude.
Atmospheric pressure, temperature, and humidity can all affect air density, and places with high temperature, altitude, and humidity have lower air density. The decrease in air density will cause a decrease in oxygen content, resulting in a decrease in engine and torque.
