Description
In addition to measuring air temperature and relative humidity in rooms and air ducts, this thermo-hygrometer can also be used for diagnosing humidifiers in air conditioning systems. When used together with the infrared thermometer testo 805i, you can also identify areas at risk of condensation and mold formation using traffic-light color coding and a special measurement mode in the mobile app.
Measure even more efficiently with the mobile app
The testo 605i transmits measured values via Bluetooth to your smartphone or tablet. By installing the **testo Smart Probes** app on your mobile device, you can conveniently view measurement data. The app also allows automatic calculation of dew point and wet-bulb temperature. All measured values are displayed in tables or graphs and can be exported into a report, which can then be sent via email as PDF or Excel files.
System Requirements:
- iOS 8.3 or higher
- Android 4.3 or higher
- Bluetooth 4.0 or higher
