The HR-45A surface Rockwell hardness tester uses a relatively low test force and is designed to test fine, small, and thin specimens that cannot be tested with standard Rockwell hardness testers, as well as workpieces with surface-hardened layers and those requiring the smallest possible indentations.
The HR-150A Manual Rockwell Hardness Tester is a standard Rockwell hardness tester. It features a mechanical, manual testing mechanism that requires no power source, making it suitable for a wide range of applications. It is easy to operate and offers excellent value and practicality.
The XHR-150 Plastic Rockwell Hardness Tester is a device specifically designed to measure the hardness of non-metallic materials, such as plastics, hard rubber, synthetic resins, friction materials, and softer metals. It employs a mechanical, manual testing method that requires no power source. With a wide range of applications and simple operation, it offers excellent cost-effectiveness and practicality.
Accuracy complies with GB/T 230.2, ISO 6508-2, and ASTM E18.
HR-45A Surface Rockwell Hardness Tester
1. Surface-hardened steel, copper, aluminum alloy sheets, steel strips, cemented carbide steel, galvanized, chrome-plated, and tin-plated materials;
2. Various metallic materials that have undergone surface heat treatment or chemical surface treatment.
HR-150A Standard Rockwell Hardness Tester
1. Determination of Rockwell hardness for ferrous metals, non-ferrous metals, and non-metallic materials;
2. Measurement of Rockwell hardness for 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.
XHR-150 Plastic Rockwell Hardness Tester
1. For testing plastics, composite materials, and various friction materials;
2. For testing the hardness of soft metals and soft non-metallic materials.
1. Utilizes a mechanical manual testing method that requires no power source, offering broad applicability, simple operation, and excellent cost-effectiveness and practicality;
2. The body is made of high-quality cast iron in a single-pour casting process and features an automotive-grade paint finish, resulting in a smooth and aesthetically pleasing appearance;
3. Hardness values can be read directly from the dial, with optional scales for other Rockwell hardness grades available;
4. Features a frictionless spindle for high testing force accuracy;
5. Features a precision hydraulic buffer cast as a single unit, preventing fluid leakage and ensuring smooth, shock-free loading and unloading with adjustable speed;
6. Accuracy complies with GB/T 230.2, ISO 6508-2, and ASTM E18 standards.
