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 Battery Operational Temperature Limits.
Relative Humidity 2%RH 0.1 %RH 10 to 90% 25°C noncondensing To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

Response Time & Display Update Display updates every 1 second. After exposure to large environmental changes, all sensors require an equilibration period to reach stated accuracy. Measurements employing RH may require longer periods particularly after prolonged exposure to very high or very low humidity. WBGT requires about 8 minutes to reach 95% accuracy and about 15 minutes to reach 99% accuracy after exposure to large environmental changes.
Data Storage Logged history stored for every measured value. Auto-store interval settable from 2 seconds to 12 hours*, overwrite on or off. D1: >13,000 data points, D2: >7,000 data points, D3: >6,000 data points.
Bluetooth® Data Connect Option Wireless range up to 100ft|30m. Compatible with Kestrel LiNK app for iOS (model 4s and later) and select Android products (Android 4.3 and higher) (See website for complete list of compatible 3rd party apps).

  1. Using Kestrel DROP to Measure Heat Index for Horses Using Kestrel DROP to Measure Heat Index for Horses When it's hot and humid, humans aren’t the only species that suffer from overheating. Horses and other livestock feel the discomfort of heat and humidity, and measuring heat index with Kestrel DROP D2AG can help protect your horses.
  2. Tips for Measuring Temperature Inversions Tips for Measuring Temperature Inversions Farmers and ranchers must manage many tasks and responsibilities to successfully maintain an agriculture operation. One of the most challenging aspects to plan for and manage is the impact of ever- changing and unpredictable weather.
  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
