Product Details

Model overview

HRD-150 digital rockwell hardness tester is an electric rockwell hardness tester.The motor controls the loading, maintenance and unloading of the test force.The operation is simple and quick, except for the dial to zero, there is no artificial error, which has high sensitivity and stability.

 

Product features

The body part of the product is molded by casting process and has been treated for a long time.Compared with the jigging process, the long-term use of the shape variable is very small, and can be effectively adapted to various harsh environments;

Car paint, high quality paint, strong resistance to scratch, use many years still bright as new;

Using the frictionless main shaft, the lever is loaded, the test force precision is high;

The dial can read the hardness value directly, and can choose the other ruler of Lowell;

The core parts are all CNC machine tools, the precision and stability of the machine are greatly improved.

The manual operation error of manual rockwell hardness tester is eliminated by controlling the loading, maintenance and unloading of the test force through the motor.

The accuracy is in accordance with GB/T230.2, iso6508-2 and ASTM E18.

 

 

Range of application

Widely used in the determination of black metal, nonferrous metals, non-metallic materials of rockwell hardness.

It is mainly used for quenching and tempering heat treatment of materials such as rockwell hardness measurements, such as cemented carbide, carburizing steel, hardened steel, surface hardened steel, hard steel casting, aluminum alloy, copper alloy, malleable pieces, mild steel, quenched and tempered steel, annealed steel, bearings and other materials.
