Description
The Testo 176 H1 temperature and humidity data logger is a heavy-duty, 4-channel industrial instrument engineered for the continuous tracking of structural ambient environments, storage facilities, and building climate damage metrics. Featuring dual external probe connections supporting up to two optional NTC or capacitive humidity sensors simultaneously, it delivers prompt multi-point evaluation for precise mould growth diagnostics and thermal profiling. Built inside a robust, IP65-rated tamper-proof plastic enclosure, the system contains an extensive non-volatile data memory that records up to 2,000,000 measuring values alongside a high-durability lithium cell backing an 8-year service cycle. Profiles and logged parameters are evaluated smoothly over USB or SD card setups across three scalable ComSoft software platforms, meeting strict 21 CFR Part 11 validation protocols for the medical sector.
Industrial Applications
- Automated long-term ambient air logging and threshold documentation in industrial warehouses
- Professional structural damage auditing and building climate diagnostics to determine dew point and mould root causes
- Certified temperature and moisture tracking under demanding regulatory mandates across pharmaceutical storage installations
