The testo 175 H1 data logger measures and documents the temperature and relative humidity in buildings and enclosed spaces. Thanks to the external humidity probe (stub), a fast response time is guaranteed. The lock supplied protects your data logger from unauthorized access.
Safety and convenience at all levels
The testo 175 H1 data logger guarantees high data security and reliable measurement results based on the latest measurement technology. Thanks to the large memory for up to 1 million readings and a battery life of up to 3 years, you rarely need to read out the data logger, even for shorter measurement cycles. The standard batteries (AAA) can be replaced by the user at any time if required.
Programming and evaluating the data logger for temperature and humidity
Three software versions are available for programming and reading out the data logger and for evaluating the measurement data on the PC:
ComSoft Basic software - available to download free of charge - allows quick programming of the data logger and simple data analysis
ComSoft Professional software - optionally available - offers you various options for more detailed evaluation of the temperature and humidity values
ComSoft CFR21 Part 11 software - optionally available - ideal for the special requirements in the pharmaceutical sector in accordance with CFR 21 Part 11
Attention: To program the data logger, you need a USB cable, which is not included in the scope of delivery. Stored measurement data is transferred from the data logger to the PC via USB cable or SD card - both can be ordered as accessories when purchasing your testo 175 H1.
The professional data logger is used wherever you need absolute control over the temperature and humidity values in closed rooms: whether you want to monitor the building climate, check the storage and archive climate or find the ideal working climate. The external humidity sensor (stub) permanently connected to the housing guarantees a fast response time.
