Скачать или смотреть Mitutoyo 500-196-30 Digital Caliper Disappeared from Amazon (and It’s Bigger Than You Think)

The Mitutoyo 500-196-30 digital caliper was once one of the best-selling precision tools on Amazon — moving thousands of units every month. Now? It’s gone. And it’s not just Mitutoyo. Mahr, Fowler, Starrett, and other top metrology manufacturers have had products vanish from Amazon overnight.

In this video, I break down the surprising reason why — starting with the tragic story of Reese Hamsmith, the creation of Reese’s Law, and how new safety standards like UL 4200A-2023 have disrupted the entire metrology industry.

If you work in manufacturing, quality control, or just rely on precision measurement tools, this is something you need to know.
