Kestrel 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, manufactures 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, 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.

Built to Kestrel’s brand-specific rugged durability standard, the Kestrel DROPs are waterproof (IP67 standard can be submerged in 1M of water for 30 minutes) and drop-tested to MIL-STD-810G. Users are also able to set threshold alarms where an in-app pop-up will notify a user in a range that certain measurement criteria have been met.

We buried one 4 inches in clay soil and was able to read the signal December – April. (We also buried at 10 and 40 inches, not able to connect until I dug them up!!) Sprayed them off, replaced the battery, good as new! If someone wants to bury a DROP, we recommend the D1 as there are fewer openings for water penetration. Our spec states we are rated IP67 waterproof for 30 minutes; so as long as they are not "submerged" they should be okay. A user could always place one in a Ziploc bag if they feared standing water for longer durations of time.
