Has anyone ever used one of these two items? I am looking for something like this but the scale needs to be at leaast 22 mm, and I can't find in the specifications on all the different ones what the max scale is.
Has anyone seen one with a scale of at least 22 mm?

re: Measuring Loupe
I think this item on amazon is sort of what you are looking for

Here's the one I have. It has two scales that measure either up to one inch or 25 millimeters. It folds flat. I bought it many years ago at Hobby Lobby. There is no name on it on which company marketed it. I prefer a standard jeweler's loupe, but like you said, it only goes up to 20 mm.
I use one similar to the second one pictured which I purchased from Peak Optical. It was not cheap, but the scale on the reticule has a total length of 30 mm (and is marked at 0.1 mm intervals.)
