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.  Other information including adjustable threshold values, breached thresholds and remaining battery power can also be read off the large, clear display.



Security and comfort on all levels

The data logger testo 175 H1 ensures a high level of data security and reliable measurements based on leading-edge technology. It has a super-size memory that can save up to 1 million readings and an extended battery life of up to 3 years. This gives you the freedom to read out the data at longer intervals, even when the measuring cycles are shorter. The triple AAA batteries included in the scope of supply can be easily replaced by the user.
