Product Description
Kestrel DROP D2AG
The Kestrel DROP D2AG Livestock Heat Stress data logger is a cost effective, extremely durable and easy to use temperature and humidity data logger with additional Temperature Humidity Index (THI) calculations for livestock and feed storage monitoring. They can be used in the barn, during transport, or anywhere livestock are housed.
You can access data and chart real-time using the free Kestrel Connect App and download data in .csv format
The DROP D2AG logger is IP67 rated (30-minute submersion at 1m) and MIL-STD-810G drop tested making it ideal for remote locations, inside or outside. The Kestrel Connect App allows data to be viewed from your connected device up to 100ft away.
Each unit comes complete with a user replaceable CR2032 Coin Cell Battery (average life 300 hours) and is equipped with a sturdy D-ring for hanging wherever needed.

Sensors
| Sensors | Accuracy (+/-) |
Resolution | Specification Range | Notes |
| Ambient Temperature | 0.9 °F 0.5 °C |
0.1 °F 0.1 °C |
14 to 131 °F -10 to 55 °C |
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. |
| Pressure | 1.5 hPa|mbar 0.044 inHg 0.022 PSI |
0.1 hPa|mbar 0.01 inHg 0.01 PSI |
25°C/77°F 700-1100 hPa|mbar 20.67-32.48 in Hg 10.15-15.95 PSI |
Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product. |

Additional Product Info
| 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). |
| Certifications | CE certified, RoHS, FCC, IC tested and WEEE compliant. Individually tested to NIST-traceable standards. |
| Origin | Designed and manufactured in the USA from US and imported components. Complies with Regional Value Content and Tariff Code Transformation requirements for NAFTA Preference Criterion B. |
| Battery | User-replaceable CR2032 (included). |
| Shock Resistance | MIL-STD-810g, Transit Shock, Method 516.6 Procedure IV; unit only; impact may damage replaceable impeller. |
| Sealing | Waterproof (IP67 and NEMA-6) |
| Battery Operational Temperature Limits | 0° F to 140 ° F | -18 °C to 60°C Measurements may be taken beyond the limits of the operational temperature range of batteries by maintaining the unit within the operational range and then exposing it to the more extreme environment for the minimum time necessary to take reading. |
| Storage Temperature | -22.0 °F to 140.0 °F | -30.0 °C to 60.0 °C |
| Size & Weight | 2.4 x 1.8 x 0.9 in | 6 x 4.5 x 2.3 cm 1.2oz | 34g (Lithium battery included) |
