A must-have tool for livestock producers, veterinarians and handlers.

Pocket-sized, rugged, accurate meter for assessing ventilation effectiveness, barn conditions, livestock heat stress, air speed, field microclimates, storage conditions, transportation safety, and more.

The Kestrel 5000AG is designed to meet the needs of livestock, agriculture and animal health professionals. Producers, growers, veterinarians, and consultants in every field of agriculture will gain vital information regarding micro-climate conditions needed to maximize performance and profitability. This lightweight, handheld, multi-function meter can be used inside and out for spot measurement of current conditions and also tracks and logs over 10,000 sets of time-stamped data. Clip the Kestrel 5000AG into the custom Kestrel 5 Series Rotating Vane Mount and you have a sturdy weather station that can be left in place for days or weeks.

Heat Stress Management with THI:

THI(Temperature-Humidity Index)  has been used for decades as a measure to classify heat stress risk in many livestock production and transportation operations. This measurement includes both temperature and relative humidity and is a basis for both strategic and tactical management practices which benefit animal health, productivity and well-being. The Kestrel 5000AG calculates and logs on-site THI based on user selection of either the NRC(National Research Council, 1971) or Yousef (Yousef, 1985) accepted THI calculations. Objective and accurate site-specific measurements are critical to ensuring a heat stress management strategy that is cost effective; and they're at your fingertips with the 5000AG.

Barn / Housing Ventilation Assessments:

Regardless of the type of barn/house design all livestock require proper ventilation and air movement to maximize health, growth, and comfort.  The Kestrel 5000AG provides air speed and air flow measurements to quickly quantify air movement in the vicinity of livestock, locate drafts, measure fan effectiveness and confirm duct discharge velocity. Volume air flow takes duct shape and dimensions into account and allows for accurate comparison of various locations in a system. No calculator is needed to determine airflow with the Kestrel 5000AG – a few quick menu picks and built-in averaging gives you accurate readings instantly.

Microclimate, Harvest and Storage Conditions:

Many livestock professionals also grow and store grains, hay and other feedstuffs. The Kestrel 5000AG can measure micro-climates around the farm to determine where mold and disease may be a problem, ensuring conditions are right for harvesting, drying, and storage. Leave the Kestrel 5000AG in place anywhere in th field, barn or greenhouse to get a graphical history of overnight conditions, (the Kestrel 5 Series Rotating Vane Mount and a ¼-20 camera clamp or tripod makes it easy).

Choose Kestrel LiNK Option to Add the Power of Apps:

LiNK is Kestrel’s wireless data communication system, powered by Bluetooth® low energy. Choose the Kestrel 5000AG with LiNK option and you get full iOS, Android, PC and Mac app support.  See real-time readings on your phone or tablet on a customizable dashboard up to 100’ away (line of sight). Download stored data from your Kestrel to save or share it. Plus, you can update the firmware on your Kestrel when improvements are released.

Simple communication to Windows and Mac computers is provided through the optional LiNK USB Dongle or USB Data Transfer Cable. Download your data to view, analyze and archive.  Enables firmware update of Kestrel 5 series meters.

Note:  Bluetooth® low energy is built into all recent iOS and Android devices. PC and Mac connectivity require purchase of a Kestrel LiNK USB Dongle. Non-LiNK units can be connected to PC’s and Mac’s, but NOT phones and tablets, using the Kestrel USB Data Cable.

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. Veterinarians have been purchasing Kestrel meters for years, knowing they will provide the readings they need immediately and reliably. Farmers know a Kestrel meter can help them avoid property damage, reduce livestock losses, and maximize productivity. Shouldn’t YOU be working with Kestrel?
