Hello everyone,
I was just looking at some tool catalogs, and it struck me that since
all the calipers are listed as having accuracies of plus or minus .001
in 6 inches, and most of the micrometers are listed as being plus or
minus .0005-.00015 in 1", that the calipers are just as if not a little
more than accurate as the micrometers. And a little more useful since
you get more than one inch out of them.
But, if that is the case, I don't think anyone would be spending
like 700 dollars on a set of 1-4" micrometers. Can someone enlighten me
here? Or possibly point me to some information explaining this, since
this might make for a pretty long post?
I'm also noticing that the digital stuff doesn't list the accuracies
most of the time. But then there is a set of Mitutoyo 0-6" micrometer
with interchangable anvils and the accuracy is listed as plus or
minus .0002 + .00005 x L/3 where L is the max. measuring length. Pretty
concise listing, right? Then even Starret and Brown and Sharpe will
only have the resolution listed. Very confusing. What gives here?
