Humidity measuring instrument testo 605i, in combination with a smartphone or tablet, is suitable for the measurement of air temperature and relative humidity in rooms and ducts. Together with the separately available thermal anemometer testo 405i ( 913-2575 ), cooling and heating performance can also be determined. Users can read off their measurement values comfortably in the testo Smart Probes App installed on the end device. The App also enables the automatic determination of dewpoint and wet bulb temperature. All measurement data is presented either as a diagram or in tabular form. The measurement protocols can then be sent directly as PDF or Excel files.
