General Introduction

Model: HR-150DT Motorized Rockwell Hardness Tester

HRM-45DT Motorized Superficial Rockwell Hardness Tester


Motorized Rockwell/Superficial Rockwell Hardness features an attractive design and easy operation. It can measure the Rockwell and Superficial Rockwell hardness of ferrous and non-ferrous metals.

Key Features

  • Features
  • Principle
  • Standard
  • Application

1), High measuring accuracy, reliable performance and wide applicable fields;

2), By adopting the motor driven automatic loading and unloading technique, this thoroughly eliminates human error in the operations.

  1. The indenter moves down into position on the part surface

  2. A minor load is applied and a zero reference position is established

  3. The major load is applied for a specified time period (dwell time) beyond zero

  4. The major load is released leaving the minor load applied.

Dial Analog Rockwell Hardness Tester

The resulting Rockwell number represents the difference in depth from the zero reference position as a result of the application of the major load.


ASTM E18 “Standard Test Methods for Rockwell Hardness of Metallic Materials”

ISO 6508 “Metallic materials — Rockwell hardness test”

ASTM D785 “Standard Test Method for Rockwell Hardness of Plastics and Electrical Insulating Materials”

● Measuring the Rockwell hardness of soft metal materials such as ferrous and non-ferrous metals;
● Measuring the Rockwell hardness of high-hardness alloy materials such as cemented carbide;
● Measuring the Rockwell hardness of heat-treated materials such as quenched and tempered metals;
● Measuring the Rockwell hardness of certain non-metallic materials such as plastics and bakelite.

● Measure the surface Rockwell hardness of soft metal materials such as ferrous and non-ferrous metals;

● Measure the surface Rockwell hardness of metals after surface treatment (carburizing, nitriding, electroplating, etc.);

● Measure the surface Rockwell hardness of materials after heat treatment such as quenching and tempering;

● Measure the surface Rockwell hardness of high-hardness alloy materials such as cemented carbide;

● Measure the surface Rockwell hardness of certain non-metallic materials such as plastics and hardboard.
