Mechanical Manual Loading Rockwell Hardness Tester with Dial
Reading Accuracy ±1.0HR
Brief Introduction:
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:
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.
Application:
1. Quenched steel, quenched and tempered steel, annealed steel,
bearing steel, strip steel, hardened steel sheet, hard alloy, etc.;
