Description

Digital Motorized Rockwell Hardness Tester

The Digital Motorized Rockwell Hardness Tester is a precision hardness testing machine designed for determining the hardness of metals and alloys across a wide range of applications. It is suitable for testing hard or soft metallic materials in flat, round, or irregular shapes, making it useful for industrial laboratories, quality-control departments, manufacturing facilities, and material testing laboratories.

The Rockwell Hardness Testing Machine uses the Rockwell indentation hardness principle to evaluate material hardness through controlled test loads and indentation depth measurement. The GTX-HR model provides selectable test loads of 60, 100, and 150 kgf, with an initial load of 10 kgf.

Designed for convenient operation and repeatable testing, the machine features a large LCD graphical display, motorized automatic loading, selectable manual loading, programmable dwell times, and an electronic data storage system. Up to 75 test results can be stored, along with statistical information such as mean, standard deviation, maximum, and minimum values.

Working Principle of Rockwell Hardness Testing Machine

The Digital Motorized Rockwell Hardness Tester determines material hardness by applying a specified test force through a suitable indenter and measuring the resulting indentation depth.

The test begins with an initial load of 10 kgf, followed by the selected major test load of 60, 100, or 150 kgf, depending on the Rockwell scale and material being tested. The machine controls the loading sequence and dwell time, while the indentation depth is used to determine the Rockwell hardness value.

The motorized loading system provides controlled application of the test force. After completion of the test cycle, the hardness result is displayed on the LCD screen. The machine can also store test results and calculate statistical values, making it suitable for repeated quality-control testing.

The correct indenter, load, test scale, specimen preparation, and test procedure should always be selected according to the applicable testing standard and material specification.

Benefits of Digital Motorized Rockwell Hardness Tester

The motorized operation of the GTX-HR provides controlled loading during hardness testing, while the digital display makes test results easier to monitor. The programmable dwell-time settings allow users to configure the testing cycle according to the applicable procedure.

The ability to store test results and display statistical information can also help laboratories manage repeated testing and quality-control activities.

Its range of test loads, interchangeable testing tables, supplied indenters, and test blocks make the machine suitable for different Rockwell hardness testing applications.
