Mitutoyo 12AAA222 Height Gage Adapter SJ-301 SJ-210

Product Description

The MITUTOYO 12AAA222 is a height gage adapter designed for use with Surftest portable surface roughness testers. This accessory mounts directly to compatible Mitutoyo instruments and allows the tester to be positioned and stabilized on a height gage stand, enabling consistent stylus placement during surface profile measurements. It is a purpose-built replacement and accessory part installed by metrology technicians, quality control personnel, and precision measurement professionals in manufacturing and inspection environments. The adapter measures 9.00 millimeters in overall length and 9.00 millimeters in overall depth, making it a compact interface component suited for benchtop and field inspection setups.

This adapter is intended for use in dimensional inspection and surface finish measurement applications where a height gage is used as a positioning reference. It supports precise, repeatable stylus traversal across flat, machined, or finished workpiece surfaces. Typical installation scenarios include quality lab benches, machine shop inspection stations, and in-process measurement setups where the SJ-301 or SJ-210 tester must be held at a fixed, controlled elevation above the workpiece.
