Yep, invaluable. I don't honestly know if there's an accuracy difference between the digital and the dial units, but there's one digital unit (that I've had trouble with) that I see under dozens of brand names, they must be made by the millions. I actually think they're around ten bucks.
If it's close enough you need an accurate micrometer though, you're cutting the clearance pretty close!
But its the right tool, as toolboxchev said.
I probably do it wrong/different, but I cut the clay with a razor or boxcutter and then measure the thinnest part with the depth end of the micrometer.
