This temperature and humidity data logger offers configurable settings via DGraph Pro software, downloadable from the software tab. Users can initiate logging immediately or schedule a delayed start depending on monitoring requirements. Once the logging task is complete, the data logger connects to a PC via USB. The DGraph Pro software allows seamless data download in .dlg format, which can then be exported as TXT, CSV, XLS, JPG, or BMP files for flexible analysis and reporting.
Real-time monitoring is supported, enabling live temperature and humidity display directly on the computer during logging. This feature enhances on-site analysis and operational visibility. The device also records dew point temperature, which is included in the exported datasets and viewable through the software for further environmental diagnostics.
Each unit is shipped with a calibration certificate from an ISO/IEC 17025:2017-conforming lab, ensuring accuracy and traceability to SI units through NIST. Recalibration of both temperature and humidity parameters can be performed through the DGraph Pro software at two calibration points, either in qualified labs or through STN Instruments’ calibration service.
Ideal for laboratories, warehouses, production areas, and HVAC systems, this logger offers long-term performance with reliable accuracy, efficient data export, and real-time diagnostics for diverse environmental monitoring needs.
