Evening all,

Im just having a tidy up and checking over my mics and gage blocks. So far the mic measures a selection of the gages correctly, so if they are wrong both of them have the same coincidental errors…

Anyway whilst cleaning and putting the blocks away I wondered how they manage to get such a perfect surface finish at such a (relatively) low cost?

Anyone got good links or info ?

I can’t help regarding manufacture, Dave … but NPL has some impressive information about calibration!

… just put ‘gauge blocks’ in their search box, or start here:
