Kestrel 5000AG Meter Description
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.
When combined with the Kestrel Vane Mount and Kestrel Tripod the Kestrel 5000AG becomes a stand-alone farm environmental monitoring station as the large wind vane and precision pivot keep the Kestrel oriented into the wind for continuous measurement and logging of all key environmental parameters. With a storage capacity over 10,000 sets of time-stamped data this robust weather station can be left in place for days or weeks.
There are two versions of Kestrel 5000AG:
• With the standard Kestrel 5000AG data can be transferred using the K5000 USB Data Transfer Cable (sold separately) to a Windows/Mac device. The free of charge Kestrel LiNK App will allow you to view and hold all data as well as download into .csv format. • The Kestrel 5000AG LiNK version has Bluetooth connectivity allowing you to transfer data wirelessly to an iOS (iPhone, iPad) device or Android smartphone or tablet when within range using the appropriate Kestrel LiNK App. You can also transfer data wirelessly to a Windows or Mac computer using the optional Kestrel Bluetooth USB Dongle (sold separately). Data can be viewed live on the App up to 100 feet away (line of sight).
When combined with the Kestrel Vane Mount and Kestrel Tripod the Kestrel 5000AG becomes a stand-alone monitoring station as the large wind vane and precision pivot keep the Kestrel oriented into the wind for continuous measurement and logging of wind speed and all other key environmental parameters.
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 mould and disease may be a problem, ensuring conditions are right for harvesting, drying, and storage. Leave the Kestrel 5000AG in place anywhere in the field, barn or greenhouse to get a graphical history of overnight conditions, the K5000 Vane and Mount with Kestrel Tripod create a stand-alone monitoring station.
Mil-SPEC-810G drop tested with an IP67 waterproof rating the Kestrel 5000 is designed and constructed to withstand the harsh working environment it will encounter on farms. The unit comes with a five-year warranty and certificate of conformity as standard.

Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min| 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5° off-axis; -2% @ 10°; -3% @ 15°. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. Measuring wind speeds above 60 m/s / 134.2 mph can damage the impeller. *F/S only in Ballistics units. Beaufort not available in Ballistics units.

Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Display & Battery Operational Temperature Limits
