Micrometer with digital counter 25-50 mm

Painted frame with hard metal contacts. Reading is made easier by the careful execution of the characters and the engraving depth. The spindle screw rod machining is particularly accurate, obtained in an environment kept at 20°C. The screw is fully hardened and stabilized; after roughing the thread, it is subjected to a special ageing treatment before finishing, to avoid variations due to residual internal stresses. Contact surfaces are super-finished to Ra 0.025 µm.

Easily accessible locking device. Thermal insulation plates applied to the frame. Steel lamina friction which, depending on size and position on the drum, meets the dual requirement of accessibility both on the support (see art. SUM) and in the more frequent use with the workpiece and the instrument held in hand. They feature a digital counter reading system that makes them extremely easy to use, even for non-expert personnel. Frame with thermal insulation. Hard metal contacts.
