- High level of data security Large, easily legible display
- Measurement data memory for 1 million measurement values Up to 3 years‘ battery life
- Data transfer via USB cable or SD card
- External capacitive humidity sensor for faster response to environmental changes
The testo 175 H1 temperature and humidity logger has an external stub sensor designed for long term reading stability. This logger’s internal memory will hold up to 1 million readings, which equates to 15 minute reading intervals for 10,416 days, or over 28 years.
The 175 H1 logger is especially perfect for monitoring long term ambient conditions in museums, laboratories, hospitals, or office buildings.
Testo 175 loggers can be programmed, analyzed, and have data retrieved with the ComSoft Basic 5 software (free download), as well as the more sophisticated ComSoft Pro and ComSoft CFR programs.
Testo Inc. also offers NIST calibration services for testo 175 H1 and other loggers.
