Testo 625 Thermohygrometer

The Testo 625 is a compact thermohygrometer that measures air temperature and relative humidity simultaneously, and calculates dew point and wet bulb temperature quickly and accurately. It comes into its own wherever the right indoor climate is critical — archives, server rooms, greenhouses, libraries and commercial buildings.

The Testo 625 features a connectable humidity range sensor, a large backlit display, a hold function to freeze the last reading, and min/max recall at the touch of a key. A battery-friendly auto power-off mode and long-life moisture sensor ensure reliable results for years of field use.
