Multi-function digital twin Rockwell hardness tester has high level automation, stable and reliable performance, it can meet the Rockwell hardness test requirements of all metal materials. it is equipped with sophisticated sensors so that can test data more accurate ; 5.6 inch digital LCD screen provide comprehensive data for quality control. It is easy to preserve the data for a long time.

 

Main function and features 

1. The machine can meet the metal Rockwell and superficial Rockwell hardness test requirements; high test precision ;good repeatability;

2. Equip with sophisticated sensors, more accurate test results, leading load structure design, can easily switch test force;

3.  It is automatic to test when the workbench lift up to certain height, then indicate the hardness value and test data directly;

4. With Chinese and English operation interface, can be set in test method quickly, the upgraded control system is more stable;

5.  Indicate the hardness value, hardness unit, conversion hardness, test force, indenter type, minimum thickness, dwell time, test number, test process on the LCD screen directly; Built-in printer can print the measure count, hardness value, average value, maximum and minimum values, range data for our customer;

6.One-time casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh environment; the shell coating adopted car paint technology with white color. it has strong scratch resistance capability and still look bright as new after use many years;
