Kestrel Pocket Weather Meters & Construction/Building Trades

For Concrete Workers:

Plastic shrinkage cracks occur when the surface of the concrete dries rapidly and shrinks before it can gain sufficient tensile strength to resist cracking. When ambient conditions and concrete temperatures combine to produce conditions that create a high evaporation rate, the chances of the surface drying prematurely and shrinkage cracks forming increases. Measuring the relative humidity, ambient temperature and wind velocity right where the concrete is being placed can help prevent plastic shrinkage from occurring, and a Kestrel 4300 is the perfect solution. Accurate, quick-response readings give concrete professionals the information that they need to place concrete that won’t crack. Or take advantage of the Kestrel 4000’s data log and document that the work was done during the appropriate conditions.

For Heating, Ventilation, Air Conditioning and Refrigeration (HVAC/R) Workers:

HVAC/R system commissioning and verification can determine that a system is working correctly, or can identify a problem area in a faulty system. Volume air flow is a calculation based on the air velocity and the size of the area that it’s flowing out of, and is one of the most important measurements HVAC/R professionals require. Previously, technicians were forced to determine the area of the duct and then calculate the CFM. Kestrel Pocket Air Flow Trackers automatically calculate the CFM, making the technician’s job easier and faster. The Kestrel 4100 was the first device to offer this automatic feature, and was awarded the prestigious Dealer Design Award, recognizing it as a testing product that helped technicians save time on the job. The new Kestrel 4200 also measures grains per pound, and is quickly becoming an essential piece of equipment for the dehumidification and mold inspection and remediation professional. Both the 4100 and 4200 also feature a powerful 1400+ point data logger, and are totally customizable with User Screens that allow technicians to program their Kestrel Tracker to display any three readings simultaneously.

For Home Inspectors:

A large portion of any home inspection will be dedicated to examining the heating and air conditioning systems. A Kestrel Pocket Air Flow Tracker is an invaluable tool for home inspectors for all the same reasons that they are commonly found in HVAC technicians’ tool boxes. Quickly checking the consistency of warm and/or cool air in each room is as easy as entering the duct size and holding the Kestrel in the air flow. The Kestrel 4200 can even help home inspectors with mold and allergen testing. Both the Kestrel 4100 and 4200 log data with the press of a button, allowing home inspectors to save data and review it back at the office when writing up their report.

For Exterior Painters:

General contractors are constantly using materials that are temperature sensitive. From Bondo to exterior paint, they need to ensure that the environmental conditions are conducive to curing. For example, paint the exterior of a house when it’s too cold or humid, and the paint will end up peeling. And temperature is even more important when painting porous materials - like brick – since it absorbs and retains both heat and cold. A Kestrel is small and rugged enough to keep in the glove box of the truck, ready for checking the conditions on questionable days.

For Crane Operators:

Strong winds impose additional loads on a mobile crane and affect the crane’s stability, and most manufacturers state the maximum wind speed limits for each specific crane. Operators must take into consideration the boom length and height of the load when assessing windy conditions, and gusting wind affects a crane differently than a constant wind. Additional influences that jeopardize the safety of operating a crane in windy conditions are the wind direction, as well as surrounding structures that can cause a “tunnel effect”. The Kestrel's patented impeller gives crane operators the crucial wind speed data they need, accurately and instantly. When in the Max Wind mode, the Kestrel Meter will store the strongest gust. In cold conditions, the Kestrel gives the vital temperature and wind chill data needed to assess shock loading, crane hydraulics, and derating of the crane, as well as the safety of the personnel working in the cold conditions.
