Kestrel 4300 Construction Weather Tracker at $259.00 with FREE shipping, is a big help with activities such as decorative concrete, Ready Mix Concrete (RCM) and Tilt-up concrete.
Evaporation rate is a critical environmental indicator that concrete contractors use to ensure they avoid plastic shrinkage cracks in concrete installations especially concrete flatwork. Plastic shrinkage cracks occur when the surface of the concrete dries too quickly and shrinks before the bed has cured enough to resist cracking. This is especially relevant in specialty applications like decorative concrete, Ready Mix Concrete (RCM) and Tilt-up concrete.
The Kestrel 4300 measures evaporation rate, relative humidity, current, maximum or average wind speed, temperature, dew point, barometric pressure, heat stress index and wet bulb temperature. Additionally, it measures wind chill, altitude, density altitude and features a 1800-point data logger
