HR series Rockwell hardness tester for ferrous and non-ferrous metals and heat-treated parts after quenching and tempering.
Overview
The HR series HR Series Rockwell Hardness Tester is used for Rockwell hardness testing of ferrous metals, non-ferrous metals, non-metallic materials and cemented carbides. It is suitable for hardness inspection after heat treatments such as quenching, tempering and conditioning. It is widely used in machinery manufacturing, automobile, aerospace, iron and steel, building materials, quality inspection institutions and laboratories. This series adopts the Rockwell indentation measurement principle and features compact structure, convenient operation, rapid measurement and stable data.

FAQ
Q1: What standards does the HR Series Rockwell Hardness Tester comply with?
A1: The HR Series Rockwell Hardness Tester is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the HR Series Rockwell Hardness Tester be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
