The Testo 605i (0560 2605 03) Smart Probe Thermo-Hygrometer with Extended Bluetooth Range, -4° to 140 °F, is a humidity and temperature measuring instrument that quickly and accurately measures relative humidity, dew point, and temperature in rooms, ducts, registers, and environmental boxes/chambers. Users can read the measurements using the testo Smart Probes App installed on their smart device. Smart Probes can be used individually or combined with other Smart Probes to create measuring solutions for most HVAC/R applications. The 605i is excellent for setup and diagnostics of large and small HVAC/R systems.

In addition to measuring air temperature and relative humidity in rooms and ducts, the thermohygrometer is also suitable for checking air conditioning system humidifiers. When you use the testo 605i in conjunction with the testo 805i infrared thermometer (sold separately), you can clearly identify areas susceptible to mould via the traffic light principle, with the assistance of a measurement menu that is already stored in the App.

The testo 605i works on smart devices with either Android or Apple operating systems, wirelessly transmitting the measurement data via Bluetooth from up to 350 feet. With the testo Smart Probes App installed on your terminal device, you can view your readings conveniently. The Testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six Smart Probes and to easily document and 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 shared by email. All your data can be stored and retrieved, saving you hours of time-consuming paperwork.
