Embedded Software and Data Receiver

Sigma Base comes with a powerful integrated software that guides the user in the measurements and shows the results on the integrated screen. Data can be also stored in PC with Data Receiver software for additional data storage and reporting.

Integrated Software

  • Standalone operation

    Run measurements and view results directly on the instrument screen, with no external computer required.

  • Intuitive workflow

    A clear, user-friendly interface makes the instrument easy to operate right out of the box, with minimal training needed.

  • Reliable results and flexible data handling

    A high-end digital balance supports precise measurements, while results can be viewed onscreen, transferred to a PC, or printed using an optional printer.
