Mitutoyo 12AAA210 Detector Extension Rod 50mm for SJ-210 SJ-310 Surface Roughness Testers

The Mitutoyo 12AAA210 is a 1.97-inch (50mm) detector extension rod designed specifically for use with SJ-210 and SJ-310 surface roughness measuring instruments. This precision accessory allows operators to extend the reach of the detector unit for measuring surface finish in hard-to-access areas or deep recesses.

Key Features:

• Extends detector length by 50mm (1.97 inches) for improved accessibility
• Maintains measurement accuracy when properly installed
• Compatible with SJ-210 and SJ-310 surface roughness tester models
• Direct replacement accessory for Mitutoyo portable roughness testers
• Precision-manufactured to Mitutoyo quality standards

Important Compatibility Notes:

• Not compatible with transverse tracing drive unit models
• Only one extension rod should be used at a time to maintain measurement accuracy
• Designed for standard (non-transverse) detector configurations only

This extension rod is an essential accessory for quality control professionals and machinists who need to measure surface roughness in confined spaces or on larger workpieces where the standard detector reach is insufficient.
