About the Kestrel 5200 Professional Environmental Meter

The Kestrel 5200 eliminates the guesswork from difficult projects like pouring concrete, balancing HVAC systems, and monitoring job site conditions with its integrated specialty calculations.

The Kestrel 5200 offers advanced calculators and readings that are unique in the portable meter market and are designed to make your job easier. In addition to measuring current environmental conditions, the Kestrel 5200 tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to a mobile device wirelessly with the LiNK wireless communication option and Kestrel LiNK app, or to a PC/MAC with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (available separately).

Construction

The Kestrel 5200 has the American Concrete Institute Evaporation Rate nomograph built in, and displays the Evaporation Rate right on screen with no calculation or error-prone interpolation. With that information in hand, decisions about additives to the mix or curing adjustments can be made, prevent costly plastic shrinkage cracks of the slab. Plus, the Kestrel 5200 allows you to monitor wind-loading on booms and cranes, and even track the heat index on your work site to keep your workers safe.

HVAC

Volume air flow couldn’t get any easier than this. Simply input the duct shape and dimensions and traverse the Kestrel 5200 across the duct. You’ll get instantaneous and average volume air flow without the need for any geometry or calculations. readings that greatly assist in commissioning and performance balancing HVAC systems. While not a replacement for a balometer, the Kestrel 5200 is far less expensive and can save you time and money. The Kestrel 5200 also offers every commonly-used measurement of moisture content in air, making life easy to determine dehumidification needs.

LiNK (Bluetooth)

The 5200 with LiNK Bluetooth Connectivity, gives you the option to transfer data wirelessly to an iOS (iPhone, iPad) device or Android smartphone or tablet when within range using the appropriate app (See Below). Also with the 5200 with LiNK Meter, you can transfer data wirelessly to a Windows or Mac computer using the optional Kestrel Bluetooth USB Dongle.
