The compact Testo 605i temperature and humidity measuring instrument with bendable probe head features professional measuring technology in an intelligent format:
it can be used in conjunction with a smartphone/tablet and the Testo Smart Probes App to reliably measure air temperature and humidity in rooms and ducts.
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, 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.
Measure more efficiently using the App
The Testo 605i wirelessly transmits the measurement data via Bluetooth to your own smartphone or tablet. With the Testo Smart Probes App installed on your terminal device, you can view your readings conveniently.
The app also enables the dew point and wet bulb temperature to be determined automatically. All measurement data are presented either as a diagram or a table. Finally, the measurement data report can be e-mailed directly as a pdf or Excel file.
*Our tip: Use the Testo 605i as a probe in conjunction with the appropriate IAQ measuring instrument from Testo.
