How does that gauge work then?
The pincers on the end of the guage go either side of the rim and the pointer at the other end registers the rim thickness on the scale.

The front wheel rim thickness on my fixed varies between 1.5 and 1.25 mm. It looks like it will be OK for the rest of this winter but it'll need changing before I use it next winter, I'll be keeping an eye on it for now.

I am quite encouraged by this thread. I have never worn through a rim, being a bit on the heavy side, I am much more used to cracking rims between spoke holes. I do, though, have a pair of "tough as old boots" Campagnolo Sciroccos, which are getting spectacularly concave, on one of my winter Bianchis. I think I will keep riding them till they go in holes!

Y old fashioned Eyeball Mk1 can see that is borked from dozens of miles away.

I use the straight edge of a steel rule, but have never yet needed to replace a rim.
