560RSS digital dual Rockwell hardness tester
Introduction: The digital dual Rockwell hardness tester has a novel appearance, complete functions, easy operation, clear and intuitive display, and stable performance. It is a high-tech product that integrates mechanics and electronics, and can perform hardness testing on all Rockwell and surface Rockwell scales.

Its main functions are as follows:
1. Selection of all Rockwell and surface Rockwell hardness scales;
Conversion values between two hardness scales;
3. Selection of holding time for hardness testing;
4 years, months, and days of modification;
5 domain value settings;
6 RS232 serial communication for users to expand functionality.
This hardness tester also has a storage function and can browse the hardness testing page. The hardness test results can be printed out.
