Just to be pedantic - the WR100 is +-0.001 officially. They say it's "accurate to a thousandth of an inch", but that's not quite right. It would have to be +-0

Just to be pedantic - the WR100 is +-0.001 officially.
They say it's "accurate to a thousandth of an inch", but that's not quite right.
It would have to be +-0.0005 to be actually accurate to a thousandth of an inch.
It's accurate to 2 thousandths.
So for example, the differences seen between a number of manufactures in the "width standard deviation table" are totally in the error bars (IE CC translucent vs koplow, gamescience vs cc opaque)
I also strongly doubt the wixey's used are really accurate to 2 thousandths, either.
I have a few of them, and i measured some master gage blocks with the wixeys (WR-100's) and some mitutoyos .
One wixey wr-100 was +-.003, another +-0.004 (IE out of spec).
The mitutoyo's were +-.0002 (in spec)
Don't get me wrong, Wixey is a good product at a very good price, but if you are trying to measure at the 0.00X level with some repeatability, probably not the right choice.
