Main Features
- 6-inch touch screen display or computer display, Chinese and English menus, rich menu content, with a super-domain warning system.
- Automatic loading and unloading of load, simple operation, a high degree of automation.
- Hardness automatic display, high accuracy, small indication resolution, no artificial operation error.
- It can automatically identify the minimum thickness and super-domain warning of the specimen.
- It has a built-in micro printer, which can print average hardness, maximum and minimum hardness, and its hardness has discreteness.
- The RS232 interface can be connected with computer to save massive data and hardness analysis.
- It has an automatic conversion with other hardness. (HB, HV, etc.)
- It has one national intellectual property right.
Application Range
- Rockwell: It is used to measure Rockwell hardness of ferrous, nonferrous metals and nonmetallic materials. It is suitable for measuring Rockwell hardness of heat treatment materials such as quenching and modulation.
- Surface Rockwell: It is used to measure the surface Rockwell hardness of the ferrous metal, alloy steel, hard alloy, and metal after surface treatment (carburizing, nitriding and electroplating).
- Plastic Rockwell: Hard plastics, aluminum, tin, copper, mild steel, synthetic resins, and friction materials.
