Edan U50 Prime

The Edan U50 Prime has 11 catalogued probe and guide references here — pick the one matching your probe label for its fault table. The references here are mainly Edan. The mix runs to linear, micro-convex and convex, and failure patterns follow the design — lens membrane wear and strain-relief fatigue shows up most on this kind of head. Send the full probe label photo along with the console model — revision differences matter for the assessment.
