High-Accuracy Multi-Use Temperature & Humidity Monitoring for Cold Chain & Compliance Applications
The ET-THLog Reusable Temperature & Humidity Data Logger is a precision monitoring device designed for long-term Temperature & Humidity tracking in logistics, pharmaceutical storage, laboratories, and industrial environments.
Equipped with a NIST-traceable high-accuracy sensor, reusable architecture, and automated reporting capability, ET-THLog delivers reliable environmental validation while reducing operational costs compared to single-use loggers.
- High-precision ±0.5°C accuracy; ±3%RH
- Reusable multi-use design
- EN12830 compliant monitoring
- NIST traceable sensor technology
- Automatic PDF & CSV reporting
- Supports 21 CFR compliant management software
- Industrial IP65 protection
The ET-THLog integrates a TI high-accuracy digital sensor within an optimized independent sensing cavity, ensuring fast thermal response and precise measurement performance.
Its high thermal-conductivity housing improves heat transfer efficiency, allowing faster detection of environmental changes during transportation or storage.
The device supports both web and desktop configuration software, enabling flexible deployment across enterprise monitoring systems.
High Accuracy Measurement
- ±0.5°C accuracy across −10°C to 70°C
- ±3%RH accuracy across 20%RH to 80%RH
- NIST traceable sensor calibration
Designed for easy to configure & download data without required to install software on PC.
Desktop Database Storage
Designed to facilitate the storage of data in a single or multiple databases, and to be accessible by more than one PC in the same local area network that is sharing a server or PC. The data is automatically downloaded and synchronized from each datalogger to a single database, facilitating the retrieval and backup of the data.
Reusable Cost-Efficient Design
Designed for multiple deployments, reducing recurring hardware expenses.
Advanced Compliance Support
Compatible with 21 CFR management software for regulated industries.
