Product Details

This model hardness tester is an automatic Rockwell hardness tester. After place on the specimen, the whole test process will be completed automatically, only press one key, the hardness value will be readout.

Main Features:

1. Specimen will be raised up automatically (without height limited)

2. Automatically load the initial test force

3. Automatically load the main test force

4. Automatically measure the hardness values

5. Hardness value automatically be digitally displayed

6. May test with such Rockwell scales as HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK

7. Automatically revise the measuring errors

8. Automatically hardness exchange

9. Print the test result with a built-in printer
