Internal diameter micrometer 225

Vernierprecision

Mechanical 3 points micrometer. The instrument anvils are at the same level as the measuring head for measuring blind bores. Personal judgement on the part of the operator is not required due to use of a torque limiter. When the thimble rotates, the anvils are enlarged until they make contact with the bore walls. The torque limiter ensures correct pressure so eliminating the requirement for operator judgement. Manufactured to extremely strict tolerances. Supplied in case with setting key and setting rings with “UKAS” certificates.
