I seem to remember that metric micrometers usually have a resolution of more like 10 microns. The finest useful screw thread would be around .5 mm and that would need 50 divisions on the drum(Common Imperial mikes used 40 tpi (.025" ... roughly 0.6 mm) with 25 divisions on the drum). |

| 98318 | 2002-11-13 06:50:00 | Hi... Use a bench type Digical micrometer almost daily for measuring paper & board thickness and I think it shines a light on a scale that is actually set in micron steps; - real accuracy - throughout a wide range of 250 um to 5000 um. Though to achieve this, calibration to ISO standards require 4 or 5 different levels... |
