The testo 623 thermohygrometer – technical features
The testo 623 thermohygrometer is designed to monitor the indoor temperature and humidity accurately and reliably.

The readings are saved automatically over a period of 90 days and an alarm alerts the room’s occupants when a threshold has been reached.
The large, easy-to-read display shows a variety of information including the last reading, the time and date and a 90-day statistic. This statistic allows you to carry out a long-term analysis of the indoor temperature or humidity of the room without first having to access your computer.

The elegantly designed testo 623 thermohygrometer fits seamlessly into any environment. It can be placed on a desk or table like a digital photo frame or fixed to a wall. A table and wall mount are both included.
