Mitutoyo 12AAA219 Vertical Adapter Surface Roughness Gage

Product Description

The MITUTOYO 12AAA219 is a vertical adapter accessory designed for use with Mitutoyo Surftest portable surface roughness testers. It mounts the gage in a vertical orientation, allowing technicians and calibration professionals to measure surface roughness on workpiece faces and features that are not accessible in the standard horizontal setup. The adapter is a direct-fit accessory that integrates with the instrument's existing mounting system, requiring no modification to the tester. At 1 pound, it is lightweight enough to keep the overall instrument assembly stable during measurement.

This vertical adapter is intended for use in precision metrology environments including machine shops, quality control labs, and field calibration settings. It is compatible with the SJ-301 and SJ-210 Surftest portable surface roughness testers. Metrology technicians, quality assurance inspectors, and toolroom professionals typically use this adapter when surface finish measurements must be taken on vertical or near-vertical workpiece surfaces that the standard instrument configuration cannot reach.
