INSIZE 3220-200 Inside Micrometer Economic Type 175-200 mm

INSIZE's 3220-200 analogue inside micrometer (economic type) covers 175-200 mm to an accuracy of 12 µm, with a 0.01 mm graduation. It is a type C instrument, with a 175 mm setting ring offered as an optional extra, a ratchet stop and carbide measuring faces, and it can be fitted to an optional stand and clamp. Parallelism between the two measuring faces is low, as INSIZE notes for this range.
