8.1 Multi-Use DC Voltage USB Data Logger w/ Display

Data logging, analysis, and export
This DC voltage data logger has an accuracy of ± (0.1%+1 reading) covering its range of 0 to 30V. Configuration settings can be managed through the DGraphPro software (available for download under the software tab). Once configured, simply press the button to begin logging immediately or schedule a delay, depending on your preferred configuration.   
After the logging task is completed, connect the data logger to a PC with the DGraph Pro software installed. Run the software, and click "start" to download the data for a dlg file. When the file is opened, it can then be saved as txt, csv, xls, jpg, or bmp file format.
This software allows for efficient and comprehensive data analysis and exportation to a designated location on the user's computer.
Real-time datalogging
The real-time function is also very helpful in displaying the readings on the computer as the logger monitors the voltage.
Re-calibratable assures long time use in-tolerance  
Each unit is shipped with a calibration report to assure accuracy from an ISO/IEC 17025:2017 conforming calibration laboratory and indicate traceability of measurements to the SI units through NIST. It can be recalibrated by DGraph Pro software with 2 points calibration by any lab with calibration capability (not recommended to be done by user) or our lab as well.
