Kestrel DROP D3 Wireless Temperature, Humidity, and Pressure Data Logger
estrel DROPs are small, rugged, and accurate environmental data loggers. The Kestrel Drop D1 targets many markets including Transportation, Agriculture, Firefighting, Facilities Management, Medical, Pharmaceutical, Consumer and others.
With made-in-the-USA quality standards and durability from NK, manufacturers of Kestrel Meters, the applications are endless. From measuring environmental data during cargo transport to conditions in the field for military training to feeling secure about the climate conditions in any room, shipped box, cargo, trailer, or freight container, to as simple as a room in your home or office building, you are able to measure all of these conditions even when you’re physically not there. And if you’re looking for a way to attach your DROP right where you need it, take a look at these options.
The Kestrel DROP D2 data logger can be placed wherever needed to log temperature and humidity with the data logs retrieved wirelessly and automatically to the Kestrel LiNK app when within wireless range(up to 100’ or more line of sight).

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). | ||
