Description
The Testo 175 H1 temperature and humidity data logger is engineered for highly reliable, long-term climate tracking within closed commercial structures, archival facilities, and industrial warehouses. Outfitted with an external stub probe incorporating a sensitive NTC sensor and a capacitive humidity cell, it guarantees short response times alongside precise calculation of dew point values. Featuring an exceptional internal memory module holding up to 1,000,000 measuring values and a non-volatile 3-year battery lifespan, it optimizes data security by preserving complete datasets during battery replacement routines. Configuration parameters and logging profile retrieval are executed smoothly via mini-USB or SD card interfaces utilizing standard ComSoft software modules, with options extending to CFR 21 Part 11 compliant setups for the pharmaceutical sector.
Industrial Applications
- Continuous round-the-clock indoor climate profiling and diagnostic logging in historical archives and libraries
- Tracking ambient air thresholds and preventive moisture damage documentation in industrial storage facilities
- Workplace ambient comfort verification and automated temperature auditing for facility management protocols
