Product Description
HRM-45DT Electric Superficial Rockwell Hardness Tester
The HRM-45DT Electric Superficial Rockwell Hardness Tester is a semi-automatic Rockwell hardness tester that tests the surface hardness of metal materials through electric loading and unloading. It features easier operation, small indentation, and high precision.
Scope of Application
- Surface hardened steel
- Copper and aluminum alloy sheet
- Strip steel and hard alloy steel
- Galvanized, chrome-plated, tin-plated materials
- Material surface heat treatment
- Chemical surface treatment of various metal materials

Frequently Asked Questions
1. How do you perform a hardness test?
A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter.
2. How do I find my Rockwell hardness number?
The Rockwell hardness number is calculated from the depth of permanent deformation of the indenter into the sample, i.e. the difference in indenter position before and after application of the major load. The minor and major loads can be applied using dead weights or springs.
