Steel Bridge Coating & Lining

Bridges and other large steel structures are painted with coatings that protect the integrity of the steel and prevent corrosion. Contractors and inspectors pay great attention to the atmospheric conditions since they play a large part in the success of application as well as the long-term health of the coating. Most important are ambient temperature, relative humidity and dewpoint, as well as the surface temperature of the steel. Relative humidity must be monitored since in this application different coatings and linings require different specific air moisture contents to cure. Additionally, condensation is an important consideration and by monitoring the difference between the dewpoint and the temperature before, during and after the coating process, the likelihood of condensation is easy to predict. All Kestrel 4000 series meters measure both dewpoint and temperature, and feature customizable User Screens that can be programmed to display these readings so professionals can monitor the values that they need at the same time.

Home Inspections

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.

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

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.

Exterior Painting

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 2000 is small and rugged enough to keep in the glove box of the truck, ready for checking the conditions on questionable days.

Crane Operations

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 1000’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 2000 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.
