testo 622 – Hygrometer and barometer
Product Descriptions
In addition to to temperature and humidity, the testo 622 also measures pressure, making it ideal for indoor climate monitoring. It shows the current measurement values as well as date and time in a large, clear display. It thus provides all important values ata glance. Especially in laboratories, the testo 622 is suitable for monitoring ambient conditions during calibrations or when setting up experiments.
Thanks to the long-term stable sensor, the measuring instrument provides reliable and correct measurement results even after years. The hanging and standing bracket allows flexible positioning of the instrument on a table or wall. Particularly time-saving and user friendly: The calibration and adjustment of the measuring instrument is possible directly on site with the help of the optional calibration and adjustment software.
