The testo 623 thermohygrometer measures the indoor temperature and humidity accurately and reliably. User-defined settings allow you to determine the length of the intervals - from 5 minutes to 24 hours. The readings are saved for 90 days, and an alarm warns when thresholds are reached.
The large, easy to read display shows the last reading, time, and date, and a 90-day statistic, which allows you to carry out a long-term analysis of the indoor temperature or humidity without accessing your PC.
The testo 623 thermohygrometer has a long term stable sensor that guarantees long term, high quality readings, and is elegantly designed to fit seamlessly into any environment. It can be placed on a desk or table like a photo frame, or fixed to a wall. A table and wall mount are both included.

Features:

Measures room temperature / humidity / alerts the occupants when thresholds are reached
Large, easy to read display / shows current reading / provides at-a-glance 90-day statistic snapshot
Long term stable sensor for long term / high quality readings
Table and wall mount included
