The Testo 175 H1 is a compact professional data logger for monitoring temperature, humidity and dew point. The external temperature and humidity probe creates faster reaction times in comparison to other temperature and humidity data loggers that are available in the market.
The 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.

Security and comfort on all levels
The 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.
