The Testo 605i Thermo-Hygrometer Wireless Smart Probe measures air temperature, dew point and relative humidity in rooms, ducts, registers, and environmental boxes/chambers through a bendable probe head. Newly designed 2nd Generation probe folds to 90° for easier access into grilles. Winner of the German Design Award in 2020. Users can read the measurements using the Testo Smart Probes App installed on their smart device.
The 605i testo psychrometer is also suitable for checking air conditioning system humidifiers. When you use the Testo 605i wireless hygrometer in conjunction with the Testo 805i infrared thermometer, you can identify areas susceptible to mould via the traffic light principle, with the assistance of a measurement menu that is already stored in the App.
