Know your temperature and humidity conditions anywhere with the small, rugged Kestrel DROP D2 Temperature and Humidity Logger. This small, handheld device will measure and log Temperature, Humidity, Heat Index, and Dew Point. It can then sync up with your iOS or Android device wirelessly using the handy Kestrel App. You can store thousands of data points and get months of logging on a single coin-cell battery with custom logging rate, connections, and alerts!
The Kestrel DROP D2 logger can be placed wherever needed to monitor and log temperature. The data logs are retrieved wirelessly and automatically through the Kestrel Connect app when within range (up to 100ft.) of your iOS or Android device.
Kestrel DROP data loggers are designed to be used anywhere you need to track environmental conditions. DROP loggers meet military and international standards for water, dust and shock resistance (IP-67: 30 minute submersion at 1m and MIL-STD-810G drop tested) and are equipped with a sturdy D-ring for hanging wherever needed.
The Kestrel DROP D2 employs a sealed precision thermistor mounted externally and thermally isolated for rapid response to monitor and record temperature over an operational and specification range of 14°F to 131°F (10°C to 55°C) within +/- 0.9°F (0.5°C) accuracy. The humidity specification range is from 10 to 90% Each Kestrel DROP Data Logger is powered by one easily replaceable CR2032 lithium coin cell battery that will last up to 4 months (typical conditions and logging/connection settings). The DROP D2 holds more than 13,000 temperature readings.
Kestrel LiNK is the free app that powers the DROP loggers. With Kestrel Connect, you can view real-time readings from any DROP logger within wireless range (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 log is viewable as a scrolling graph with detailed data for each logged point. The 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. Send and share real-time and logged environmental data via email, Facebook or Twitter.
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.
