The Motorized Plastic / Superficial / Standard Rockwell Hardness Tester uses a motor to control the application, holding, and release of the test force, with an adjustable hold time. It is simple and quick to operate, eliminates human error, and offers high sensitivity and stability.
Accuracy complies with GB/T 230.2, ISO 6508-2, and ASTM E18.
HRD-150
1. Rockwell hardness of ferrous metals, non-ferrous metals, and non-metallic materials;
2. Measurement of Rockwell hardness in heat-treated materials such as hardened and tempered steel, including cemented carbide, carburized steel, quenched steel, surface-hardened steel, hardened cast steel, aluminum alloys, copper alloys, malleable castings, mild steel, normalized steel, annealed steel, and bearings.
XHRD-150
1. Testing plastics, composite materials, and various friction materials;
2. Hardness of soft metals and soft non-metallic materials.
HRD-45
1. Surface-hardened steel, copper, aluminum alloy sheets, strip steel, and cemented carbide steel;
2. Various metal materials, including those with zinc, chrome, or tin plating, as well as materials that have undergone heat treatment or chemical surface treatment.
1. The motor controls the application, holding, and release of the test force, and the hold time can be set;
2. The machine body is made of high-quality cast iron in a single casting, finished with an automotive-grade paint process, resulting in a smooth and aesthetically pleasing appearance;
3. Hardness values are directly read from the dial, and other Rockwell scales are available as options;
4. A frictionless spindle is employed, ensuring high test force accuracy;
5. The motor controls the application, holding, and release of the test force, eliminating human operational errors associated with manual Rockwell hardness testers;
6. Accuracy complies with GB/T 230.2, ISO 6508-2, and ASTM E18 standards.
