Digital radius measuring tool.

Does anyone have any suggestions for a good one with a wide range?
All I can seem to find are Chinese specials.
For work so money no object.

I've made similar tools at work before where nothing off-the-shelf would do. Bowers make digital indicators which can be programmed with a function to translate the directly measured depth to a reading relevant to the fixture it's used in. One of those and a custom machined base in whatever size suits your application is the way I'd go.

What sort of radius range, and what is the segment angle available for the measurement?

Radius measuring calipers can be used if a greater than 105.3 degree segment of a circle is available for the measurement. This kind of thing:

Turns out the company that supplied the machine sell the measuring tool too

A mitutoyo one for around 3k.

Its just to calibrate some cnc section rolls to different materials, need to input the radius at certain points of a test bend.

Insize will do the job
