Product Description
The compact and elegant hygrometer designed to grace any desk, table or wall and provides you with constantly reliable temperature and humidity readings in offices, living spaces or commercial premises.
Advantages of Testo 623 hygrometer
The testo 623 hygrometer is designed to monitor the indoor temperature and relative humidity accurately and reliably. User-defined settings allow you to determine the length of the intervals between measurements – from 5 minutes to 24 hours. 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 long-term stable sensor guarantees long-term, high-quality readings aids you relying on your hygrometer for reliable readings for years to come.
