Dynamic Metal Hardness Tester 17.9–69.5 HRC Rockwell PROTESTER LS-190

The portable PROTESTER LS-190 hardness tester is designed for fast and accurate measurement of metal hardness using various scales. The dynamic measurement method provides stable results when inspecting large, heavy, or installed components that cannot be transported to a laboratory.

Its compact and lightweight design allows convenient measurements in workshop and industrial environments, as well as during on-site inspections.

Applications

The hardness tester is suitable for:

• quality control of raw materials and finished products;
• use in the mechanical engineering and metallurgical industries;
• inspection of components after heat treatment;
• use in laboratories and research and development departments;
• servicing machines and equipment;
• use in the automotive, aerospace, and energy industries;
• taking measurements directly on site.

Functionality

The device measures metal hardness using a wide range of scales:

• Rockwell C — HRC;
• Leeb — HL;
• Brinell — HB;
• Rockwell B — HRB;
• Rockwell A — HRA;
• Vickers — HV;
• Shore — HS.
