About Undalogic
We make precision electrical measurement affordable. The original µSMU grew out of years of hands-on research lab work, where SMUs were daily tools, and the miniSMU followed as a complete dual-channel lab instrument.
Assembled in the UK
Designed, assembled, and tested in-house. When you email support, you reach the person who built your instrument.
Calibrated, every unit
A calibration certificate ships in every box. No extra charge, no "calibration option" line item.
Software included, forever
Desktop and browser apps, Python and LabVIEW libraries, and firmware updates are free for the life of the instrument.
