Yamamoto Scientific Tool Laboratory Hard nester HRC-8

A tool for quickly and easily measuring metal hardness that allows you to easily find the hardness of any part, from steel materials to thin layers, by touch (CD-ROM included). In actual work sites, there are many cases where you want to know the rough hardness of an item first. Furthermore, 1. There are many items, so it is troublesome to put each one on a testing machine. 2. The shapes of the items are irregular or complex, making it almost impossible to put them on a testing machine that is primarily designed for flat surface measurement. 3. Even if you try to measure a specific part of the item, it is difficult to put it on a testing machine due to its shape. The HardNester is a scientific tool that was devised to meet the needs of such situations as a method of roughly, yet simply and accurately measuring hardness.
