Internal Measurements

Accuracy with a long service life for quality results in precision - that is the characteristic quality feature of Feinmess Suhl precision micrometers. Design, production right up to different variants for a range of applications are based on 130 years of experience. The precision micrometers for the determination of internal distances are therefore also available in different designs and with a range of length adapters, as two and three-point internal micrometers. The measuring surfaces are milled accurately even, parallel and lapped. They are available as point, line or jaw special shape. Carbide is used since measuring faces are subject to specifically great strains.
