    Kestrel 4300BT (Bluetooth) Construction Weather Tracker

    The Kestrel 4300 Construction Weather Tracker with Bluetooth is the first Kestrel wind and weather meter designed specifically for construction professionals, especially those who work with concrete and other materials that require curing. The new evaporation rate function makes the Kestrel 4300 the ideal wind and weather meter for concrete contractors. In addition, the 4300's long list of weather tracking capabilities puts instant and accurate environmental data right in the palm of your hand. The Kestrel 4300 is available with or without Bluetooth Technology to transmit data wirelessly. The Kestrel 4300 Construction Weather Tracker has all the features of the Kestrel 4000, plus evaporation Rate (for measuring concrete moisture).  The Kestrel 4300 Construction Weather & Environmental Meter 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. Plastic shrinkage cracks can be prevented by properly assessing the weather and the fresh concrete conditions. Previously, construction contractors used a Kestrel Meter to measure the relevant conditions, then referenced an American Concrete Institute chart to calculate the evaporation rate. The Kestrel 4300 Construction Weather & Environmental Meter does the work for them! The user simply enters the concrete temperature (obtained via an infrared thermometer or probe thermometer*) and the 4300 calculates the evaporation rate instantly. In addition to evaporation rate, the Kestrel 4300 remains the perfect rugged all-purpose construction weather tool, measuring and logging the following relevant weather conditions right where the workers and equipment are operating. For the best accuracy, use the Kestrel's convenient averaging mode to average the evaporation rate over the recommended 6-10 seconds. Many construction applications require documentation of conditions, which is quick and easy with the Kestrel PC Interface and accompanying software. Use the Kestrel 4300's 3600 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.

    Wagner Rapid RH 4.0 EX Concrete Testing

    New offering! NOW Available! The single-use Rapid RH® 4.0 EX gives flooring and building professionals the concrete moisture data they need to meet ASTM F2170 standards. Any complete floor system will generally consist of several “layers” that may or may not be composed of the same building material. Concrete slabs can form the foundation for wood, tile, terrazzo, bamboo, vinyl or carpet floors. Wooden subfloors support residential and office floor systems. Adhesives of various types provide the bond between layers. In every situation, the long-term success or failure of a floor rests on accurate moisture content management, and knowing how each strata of the floor system interacts with moisture.
