The Testo 605i thermo-hygrometer is a humidity and temperature smart probe that quickly and accurately measures relative humidity, dewpoint, and temperature in rooms, ducts, registers, and environmental boxes/chambers.

Users can read the measurements using the Testo Smart Probes App installed on their Android (4.3 or newer) or Apple (iOS 8.3 or newer) smart device.

The Testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six Testo smart probes and easily document/report the results. All measurement data is displayed as instrument readings, tables, or graphs. The measurements can be quickly saved as PDF or Excel files. The App creates custom reports which can be saved and/or shared by email.
