The Testo 605i is a wireless thermohygrometer designed to measure air temperature and relative humidity in rooms, ducts, and HVAC systems. Ideal for quick diagnostics and humidity checks, it also supports dew point and wet bulb calculations directly via smartphone or tablet when connected through the Testo Smart App. This compact instrument enables efficient remote readings and streamlined reporting, making it ideal for both building diagnostics and air conditioning maintenance.
The device is especially effective when used alongside the Testo 805i infrared thermometer. Together, they help identify mould-prone areas through a traffic light visual system in the app’s built-in measurement menu. Its flexible Bluetooth connectivity provides up to 100 meters of wireless range and ensures seamless integration with Android and iOS platforms (iOS 13.0+, Android 8.0+, Bluetooth 4.2+).
Designed for accuracy, the Testo 605i offers precise temperature readings in the range of -20 to +60 °C, with high sensitivity and long-term humidity stability thanks to its capacitive sensor. All readings can be visualized in table or graph format, and exported as PDF or Excel files for documentation. This makes it a practical, app-controlled solution for HVAC professionals and indoor air quality assessments.
