DROP D3

The Kestrel DROP D3 is designed to monitor and record a full suite of environmental conditions, including temperature, humidity, heat index, dew point temperature, barometric pressure, density altitude and pressure trend in a variety of indoor, outdoor and industrial applications.

Kestrel DROPs are ideal for monitoring conditions in manufacturing, transportation and shipping, shooting and hunting, facilities management, agriculture, healthcare and pharmaceutical organizations, firefighting, the military field, and recreational and in-home use. Put a DROP virtually anywhere and ensure safe conditions when you can’t be there.

Small, Accurate, Rugged and Waterproof

Each DROP measures just 1 x 1.8 x 2.4 inches (24 x 46 mm x 60 mm) and weighs just 1.2 ounces (34 grams).  DROP loggers meet military and international standards for water, dust and shock resistance (IP-67 and MIL-STD-810G) and are conveniently equipped with a sturdy D-ring for hanging wherever needed.

Log, View and Share on the Kestrel LiNK App

Kestrel LiNK is the free app that powers the DROP loggers. With Kestrel LiNK on your smart phone or tablet, you can view real-time readings from any DROP logger within wireless range (up to 100’ or more line of sight) via Bluetooth® low energy. Each phone or tablet can connect to up to 8 DROP loggers at the same time and store data logs from many more. Min/Max/Average readings are clearly displayed and the data log is viewable as a scrolling graph with detailed data for each logged point. The Kestrel LiNK app also allows adjustment of the logging interval and other settings as well as real-time threshold alerts. Readings can be updated as frequently as every 2 seconds and logging time and date are automatically updated whenever connected to your smart device.  You can also send and share real-time and logged environmental data via email, Facebook or Twitter

Requirements:

• iOS 6 installed iPhone 4s, iPad 3rd generation or iPod Touch 5th generation – or any later iOS or hardware configuration. Will not work on iPhone 4, 3GS on 3G or any earlier iPad or iPod generation.
• Android 4.3 and higher. Works with most Android devices with Bluetooth Smart®, including Samsung Galaxy, Nexus 4, Motorola Droid and other recent generation phones and tablets.  

DROP D3 Applications:

Long-Range Shooting: Long-range shooters need some of the most precise calculations in the palm of their hands in order to make extremely accurate shots in a variety of environmental conditions. Know the effects of barometric pressure and density altitude on bullet flight. 

Aviation: Constantly changing weather conditions make real-time flight decisions crucial for pilots in small aircraft and helicopters. Prevent takeoff and landing accidents by accurately measuring density altitude and adjusting flight operations depending on the area’s high or low density altitude.

Skydiving: Skydivers depend on density altitude to make decisions involving canopy size. Proficient parachutists may select smaller canopy sizes for routine jumps but may actually want to upsize to a larger canopy in high density altitudes. Higher density altitudes may also indicate a faster canopy descent.

SPECIFICATIONS:

• 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.
