Kestrel 0843B Kestrel 4300 Construction Weather Tracker with Bluetooth at $349.00 with FREE shipping, measures and displays evaporation rate a function of relative humidity, temperature and wind speed. 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.
Now, with integrated Bluetooth technology, both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA. Every Bluetooth Kestrel will include custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data, and transfer data to other applications.
Many construction applications require documentation of conditions, which is quick and easy with the Kestrel PC Interface and accompanying software. Use the 4300's 1800 data-point log to document that work was done during the appropriate conditions, then upload the data to a PC with the Kestrel PC Interface. The Kestrel Communicator software makes long-term storage, in-depth analysis and detailed charting of stored data a breeze.
Kestrel's Mini Tripod is a great companion for the 4300it measures 15 inches tall, positioning the Kestrel 4300 20 inches above the concrete, which is ideal for measuring the conditions that contribute to plastic shrinkage cracks.
