The new model HRD-45 Electric Surface Rockwell Hardness Tester uses a motor for automatic control of the loading, holding, and unloading of test force, with the option to select a hold time. It offers convenient, rapid operation without human error and demonstrates high sensitivity and stability.
1. Controlled by a motor for the loading, holding, and unloading of test force, with the ability to set a hold time.
2. The body is made of high-quality cast iron, created in a single casting, and finished with an automotive paint process, resulting in an attractive and sleek appearance.
3. The dial directly reads hardness values and can optionally accommodate other Rockwell scales.
4. Incorporates a frictionless main spindle for high testing force accuracy.
5. Utilizes a motor to control the loading, holding, and unloading of test force, eliminating human errors associated with manual Rockwell hardness testers.
6. Accuracy complies with GB/T230.2, ISO 6508-2, and the American ASTM E18 standards.
1. Surface-quenched steel, copper, aluminum alloy sheets, steel strips, and hard metal alloy steel.
2. Various metal materials subjected to galvanization, chromium plating, tin plating, surface heat treatment, and chemical surface treatment.
