Cosmetic grading

Transparent gradingincreases trust.

Proofen can train a custom AI grading model and tune the machine to your exact criteria, or you can adopt our open cosmetic grading standard: six grades from A+ to D. In both cases grading is always consistent, auditable, and ready to share with your buyers.

Functional test results from your preferred provider can be imported and linked to cosmetic reports via our platform, to create a comprehensive quality passport for every device.
