TH300洛氏硬度计Hardness tester
本硬度计为台式洛氏硬度计，采用洛氏(ROCKWELL)测量原理，用于碳钢、合金钢、铸铁、有色金属及工程塑料等材料的硬度检测，具有测试精度高，测量范围宽，主试验力自动加卸载，测量结果数字显示并自动打印或与外部计算机通讯等特点。广泛应用于计量、机械制造、冶金、化工、建材等行业的检测、科研与生产。
功能特点：本硬度计采用特殊的压头结构（俗称“凸鼻子”结构 ），除了可进行一般传统洛氏硬度计所能完成的测试外，还可能测试传统洛氏硬度计无法测到的表面，如环状、管状等零件内表面。

Hardness tester TH300 Rockwell hardness tester
The hardness tester for desktop Rockwell hardness tester, Rockwell (ROCKWELL) by measuring principle,used for carbon steel, alloy steel, hardness testing of cast iron, nonferrous metal and engineering plastics and other materials, has high accuracy, wide measuring range,automatic loading and unloading the main test force,digital display of measuring result and automatically printor with external computer communication etc.. Widely applied in measurement, machinery manufacturing,metallurgy, chemical industry, building materials industrydetection, scientific research and production.
Features: the hardness tester adopts pressure head structure of special (commonly known as "convex nose"),except for the traditional Rockwell hardness tester can complete the tests, surface may also test the traditionalRockwell hardness cannot be detected, such as ring, the inner surface of tubular parts.
