Not an area of knowledge for me Karl. And an interesting avenue to pursue if you want to better understand how manufacturers are cutting their brands.
Here's another device

I like this one because you can note the near exact point at which a measurement is taken with respect from the tip or butt of a reed, or either side.
(A measurement's only as good as knowing where you took it, right?)
That said, and with the caveat of admitting no knowledge of where you intend on taking this measuring Karl, I'd like to offer my 2 cents that I think reed duplicating (from a profile standpoint) machinery, (not measuring machinery, which Karl seeks) for those seeking to buy such things is a hunk of junk with respect to making copies of reeds that play identically.
If all you expect such a machine to do is copy contour, as you then adjust the reed as you might any purchased reeds, then okay.
Witness Vandoren cutting each reed of a brand (notice I didn't say strength) the same, within the tolerances of a human hair, likely better than the fresh blades of such a purchased machine can do, especially since manufactured reeds are always being cut quality tested. The reeds are then subject to a strength test, often a puff of air of constant air pressure, (not dissimilar in principle to a Optical Glaucoma testing machine) that notes how much the reed deflects, for purposes of categorizing the reed into its correct strength.
In short, the metaphorical "canvas" on which the reed cutter "paints" is different each time, as mother nature incorporates variability into cane.
Logic would deem that virtually identical cuts to different things yield different things. Even reeds cut from the same split piece of cylindrical cane.
