testo 175 H1 Temperature and humidity data logger

The testo 175 H1 data logger measures, monitors, and logs the temperature and relative humidity in buildings and closed rooms. 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.
The testo 175 H1 ensures a high level of data security and reliable measurements based on leading-edge technology. The logger 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.
