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. For increased ease of use, check out these accessoriesspecifically designed for hanging your DROP data logger.
Built to Kestrel’s brand specific rugged durability standard, the Kestrel DROPs are waterproof (IP67 standard) 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 range that certain measurement criteria have been met.
We buried one 4" in clay soil and acquired the signal December – April. (We also buried at 10 and 40", 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. Spec for DROPs are rated IP67 waterproof for 30 minutes; as long as they are not “submerged”. A user could always place one in a waterproof bag if they feared standing water for longer durations of time.
