These compact, multi-use data loggers are designed for reliable and accurate temperature monitoring across diverse applications. It measures temperature with an accuracy of ±0.3°C in the -40°C to 70°C range and ±0.5°C outside that range, making it ideal for general-purpose cold chain, storage, and transit environments. With IP40 or IP30 protection depending on the model, it is suitable for indoor or controlled environments.
Configuration is quick and intuitive using the PoChain software, which is available for download on the STN website. Users can set the device to begin logging immediately or after a custom delay. Once logging is complete, the device generates a PDF report automatically upon USB connection to any computer, ensuring immediate access to recorded data.
The data logger supports up to 6 marker points during measurement, allowing users to flag critical timepoints in real-time. This enables streamlined review and analysis of key temperature events.
When connected to a computer with PoChain software installed, users can export data in multiple formats—including XLS, CSV, PDF, TXT, and CIN—for flexible reporting and archiving. Files are saved directly to a user-defined location, simplifying compliance documentation.
Each unit is delivered with a calibration certificate from a laboratory conforming to ISO/IEC 17025:2017 standards, with full traceability to SI units via NIST. The device supports 2-point recalibration through the PoChain software and can be recalibrated by any qualified lab, though it is recommended to use STN’s in-house services for optimal results.
STN’s compact temperature logger is suitable for a broad range of industries including HVAC, food and pharmaceutical storage, logistics, and general environmental monitoring, offering consistent performance and compliance with industry regulations
