Overview

The Testo 175 H1 data logger measures, monitors and logs the temperature and relative humidity in buildings and closed rooms. The 175 H1 can monitor the indoor climate in buildings, storage facilities and archives and help create a comfortable climate in the workplace.

The logger comes with an external humidity sensor (stub) for shorter reaction times and a lock to prevent it from being easily stolen or tampered with.

In addition to the current temperature and humidity values, the logger can also log and display dew point values.
