testo 622 - hygrometer and barometer
testo 622 is a precision instrument for measuring air pressure, humidity and temperature. It is perfect for checking e.g. laboratory climate where this needs to be monitored and documented for quality reasons. The large, easy-to-read display shows current readings along with the date and time. It therefore provides all important data for e.g. a factory protocol in an instant. A reminder function notifies the user when the next calibration is due.
