Mechanical Manual Loading Rockwell Hardness Tester with Dial Reading Accuracy ±1.0HR
Rockwell hardness test indentation space, the distance between the centers of two adjacent indentations shall be at least three times the diameter of the Indentation.
The distance from the center of any indentation to an edge of the test piece shall be at least two and a half times the diameter of the indentation.
Rockwell hardness tester is stable and reliable performance and is a popular type Rockwell machine.
Mechanical manual test, no power;
Wide application scope, easy operation, good economy and practicality.
Main features and features:
1. The hardness value is directly read through the dial pointer, the pointer is sensitive, and the measured result is higher than the national standard;
2, The shell is made by a special sandblasting process with a one-step casting process. The structure is stable without deformation, and it can work in a relatively harsh environment. The car has a high-grade paint and a strong anti-scratch ability. It is still bright as a new product for many years.
3, We have our own R & D design, production and processing capabilities, our machine provides parts replacement and maintenance upgrades for life.
The main purpose and scope of application:
1. Quenched steel, quenched and tempered steel, annealed steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.;
