Construction professionals have been using Kestrel Meters for years to monitor the weather on the job site. Knowing accurate local weather conditions is important for worker and equipment safety and for ensuring good results with processes like surface coating and concrete pouring. Now NK has partnered with industry experts to develop a customized Kestrel instrument for construction professionals who place concrete.

The new Kestrel 4300 Construction Weather Tracker, NK's latest specialty Kestrel meter, measures and displays evaporation rate, which is 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 cracking of expensive concrete installations. Plastic shrinkage cracking occurs when the surface of the concrete dries too quickly and shrinks before the bed has cured enough to resist cracking.

We are a full service Factory Authorized Kestrel Instruments dealer. We offer a no questions asked special 90 day money back guarantee for all Kestrel Instruments products.

Previously, construction foremen have employed a Kestrel Meter to measure the relevant conditions, then referenced an American Concrete Institute chart to calculate the evaporation rate. The new Kestrel 4300 Construction Weather Tracker does the work for them! The user simply enters the concrete temperature (obtained via an IR 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.

Many construction applications require documentation of conditions which is made quick and easy with the Kestrel Interface and accompanying software. Take advantage of the 4300's 1800 data-point log and document that the work was done during the appropriate conditions, then use the Kestrel Interface to upload stored data to a PC for long-term storage, in-depth analysis and detailed charting.

For maximum accuracy when measuring the evaporation rate, measure the concrete temperature via IR or a probe thermometer, enter the concrete temperature into the Kestrel, and position the unit facing into the wind, 20 inches above the concrete. Shade the Kestrel's thermistor (temperature sensor) so it is not in direct sunlight. For the best accuracy, use the Kestrel's convenient averaging mode to average the evaporation rate over the recommended 6-10 seconds.

Kestrel's Mini Tripod is a great companion for the 4300—it measures 15 inches tall, positioning the Kestrel 4300 20 inches above the concrete.

Every Kestrel is individually calibrated to NIST-traceable standards and comes with a free Certificate of Conformity. Individual NIST certificates and recalibration are also available.
