HRS-150 Digital Rockwell Hardness Tester

1. Function

HRS-150 digital Rockwell hardness tester is used to test the Rockwell hardness of ferrous metal, nonferrous metal, nonmetal materials, quenched and tempered materials and other heat-treated materials. It is especially used for precision measurement of parallel planes.

2. Features

1. No friction spindle, high precision of test force;

2. Preload applied in place, automatic handwheel locking; automatic test process without human operation errors;

3. Automatic digital display, without human reading errors;

4. Solid construction, good rigidity, high working efficiency, accurate testing;

5. The attached printer can print the testing data immediately;

6. The test accuracy conforms to the standards of GB/T230.2 and ISO 6508-2.
