Introduction:

1) BRV-187.5S Universal Hardness Tester can be used to measure the hardness of Brinell, Rockwell, Superficial Rockwell and Vickers

2) Closed-loop structure, with high accuracy load cell ensure testing result high precision and stability

3) Automatic loading - dwell - unloading

4) Automatic pre-loading when measure the hardness of Rockwell

5) Automatic measurement for the Rockwell, Brinell and Vickers hardness values

6) The software provides the functions of hardness conversion, upper and lower limits settings and hardness rectification

7) RS232 port interface can be connected with the printer or computer

8) Permanent storage of testing results for database view (Only for HR)

9) Automatic generation of custom-made inspection report.
