The 605i thermo-hygrometer from Testo is perfect for measuring air temperature and relative humidity in rooms and ducts, as well as for checking air conditioning system humidifiers.
It wirelessly transmits the measurement data via Bluetooth to your own smartphone or tablet and, using the Testo Smart Probes App, you can view your readings conveniently on your Bluetooth device. The App also enables the dew point and wet-bulb temperature to be determined automatically.
All measurement data is displayed either as a chart or in table form and the measurement data log can be emailed directly as a PDF or Excel file.
