Tips For Taking Accurate Measurements

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. Preprogrammed THI zones are available and can aid in identification of heat stress risk category. 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.

Visit the Cattle Heat Stress Minisite for a more detailed look at the importance of managing heat stress in your cattle operations.

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. For ducts that are out of reach, use the Kestrel LiNK app to view your Kestrel mounted on an extension pole with the Kestrel 5 Series Clip (requires LiNK option).

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 the 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.

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?

  1. The Importance of Weather Monitoring for Vegetation Management The Importance of Weather Monitoring for Vegetation Management When it comes to vegetation management, environmental factors play an important role in success or failure. Planning and preparation become critical, especially when it comes to the knowing the weather conditions before and during spray application. With Kestrel weather meters, you can accurately track weather with real-time data, allowing you to make smart decisions for planning and application.
  2. Record Keeping Critical for New Spraying Standards Record Keeping Critical for New Spraying Standards Dr. Bob Wolf, Professor at Kansas State University, Wolf Consulting and Research, LLC, talks about the importance of identifying and recording onsite weather conditions before crop spraying applications.
  3. Preventing Spray Drift Dicamba has been in the headlines frequently due to the large-scale incidents of drift damage from illegal or improper application of the chemical in farming operations. The on-site weather at time of application has a significant impact on the risk of drift and should be incorporated into planning spray activities to avoid the potential risk and costly waste of spray drift.
  4. Agricultural Environmental Monitoring The Kestrel Agriculture line gives you reliable, site-specific weather data you can count on to make critical management decisions to increase yield, reduce losses, and boost profit.
  5. A Better Way to Manage Heat Stress in Dairy Cattle A Better Way to Manage Heat Stress in Dairy Cattle Heat stress is expensive. It can have a serious impact on cattle breeding efficiency, milk production, and feed intake. Keeping your cows safe and productive costs you time, effort, and money. Exactly how much does heat stress cost you in dollars and cents? Consider that dairy cattle operations can expect to lose about 10% to 35% of an animal’s current milk production during heat intense periods. Applying that reduced production rate to a herd of
