Testo 605i Gen 2 Wireless Thermohygrometer — Bendable Probe | Smartphone App
The Testo 605i Gen 2 is an updated version of the Testo 605i thermohygrometer from the Testo Smart Probes range, featuring a bendable probe head for improved access in ducts, tight spaces, and awkward measurement locations. Like the original 605i, it connects to your smartphone or tablet via Bluetooth and the testo Smart Probes App to measure air temperature and relative humidity in rooms and ducts, with automatic calculation of dew point and wet-bulb temperature.
When used with the Testo 805i infrared thermometer, the app enables mould risk identification via a traffic light principle. When used with the Testo 405i, cooling and heating output can also be calculated.
Confirm current testo Smart Probes App compatibility with your smartphone OS version before ordering. Confirm all specifications against the Testo 605i Gen 2 manufacturer’s current datasheet.
