Description

Every race car driver and pit crew member knows that changes in the weather, altitude or air can affect your car's performance. The rugged, portable and easy to use Kestrel 4250 Series Racing Weather Tracker quickly provides racers and pit crews with the most accurate and up-to-date weather data available where you need it most - at the track. It allows tuners to determine what last minute changes need to be made, giving you that competitive edge at a fraction of the cost of other systems on the market.

Even slight changes in air density, water grains, and density altitude can dramatically affect a machine's performance. With the added ability to easily measure and track these and other critical factors, such as absolute pressure, temperature, humidity, wind speed and barometric pressure, the 4250 Series leaves nothing to chance and you have everything to gain by having the extra advantage of knowing these important environmental conditions.

The Kestrel 4250 Racing Weather Tracker also features an automatic and manual data storage function, allowing you to easily keep logs of race day conditions from track to track, year to year. Designed to hold up in harsh, rugged environments, this meter is waterproof and features a backlight for low light conditions.

All Kestrel instruments are made in the USA and are backed with a Five-Year Warranty.
