The Kestrel 4300, the first Kestrel handheld device designed specifically for construction professionals, includes an evaporation rate function (necessary for concrete placement) and extensive weather tracking capabilities, giving users instant access to accurate environmental data. It also includes Bluetooth Technology for fast, easy data transmission.

The unit makes it simple to calculate the evaporation rate of concrete by taking into account ambient temperature, relative humidity and wind speed. It also includes wind speed functions for crane operators and functionality that tracks humidity measurement for painting and drywall installations.

Users can track pressure and temperature to help predict future weather conditions and ensure concrete placement or coatings are applied within stated tolerances.
