Kestrel Drop D1: your smartphone becomes a valuable thermometer

Drop D1 Kestrel

The Kestrel Drop D1 turns your smartphone into a professional thermometer for measuring temperature in any environment.


Kestrel Drop D1 transforms your iPhone or IPad into a thermometer that can detect the temperature wherever you are. The app is able to set different types of temperature readings and generate graphs or set alarms.

Kestrel Drop D1 continues to store data even when it is dissociated from your device. It can therefore be considered a stand-alone element and store the temperature of any room or container, including traveling. The stored data can then be analysed at a later date.

Kestrel Drop D1 is designed and built entirely in the USA, is waterproof IPx7, is resistant to falls according to the standard MIL-STD-810G, is very precise and is as small as a keychain.
