The testo 625 is a compact instrument with an integrated humidity probe head for the measurement of air humidity and temperature. The large two-line display quickly and reliably shows humidity, Wet Bulb temperature or dewpoint, as well as temperature.

For measurements in difficult-to-access places, the humidity probe head can simply be removed and plugged onto the handle with a probe cable (accessory); alternatively, the measurement values can be transferred wirelesly from the probe to the measuring instrument over large distances. For this purpose, the humidity probe head is plugged onto the wireless handle (accessory), and the testo 625 is equipped with the radio module (accessory).
