Testo 623 Thermohygrometer

The compact and attractive thermohygrometer is meant to complement any desk, table, or wall and gives consistent temperature and humidity readings in offices, living rooms, or commercial establishments.

The Testo 623 thermohygrometer is designed to precisely and consistently detect indoor temperature and humidity. The length of the intervals between measurements can be selected by the user, ranging from 5 minutes to 24 hours. The readings are automatically kept for 90 days, and an alarm notifies the room’s inhabitants when a threshold is crossed.

The wide, easy-to-read display displays a variety of data, including the most recent reading, the time and date, and a 90-day statistic. This statistic enables you to do a long-term investigation of the room’s internal temperature or humidity without first requiring access to your computer.

The sensor’s long-term stability ensures long-term, high-quality results. You know you can count on your metre to provide you accurate readings for years to come.

The attractively designed temperature humidity display testo 623 blends into any setting. It can be hung on a wall or placed on a desk or table like a digital photo frame. Both a table and a wall mount are supplied.
