INSIDE MECHANICAL MICROMETER 3-POINT BLET STEINMEYER, MEASURING RANGE : 10-13 mm, READING : 0,5 mm

Often used for mechanical measuring diameters of cylindrical elements or layers, the outer BLET STEINMEYER precision micrometer measure all linear dimensions in two points. This palmer is composed of a fixed key and a key for mobile micrometer screw. Excellent accuracy. Vernier reading, sometimes supplemented with a meter. Or the ratchet torque limiter, integrated over some, allows an identical clamping for each measurement. Regulating the strength of the outside micrometer BLET STEINMEYER obtained by ratchet.
