Model Hrss-150 On-Line Automatic Rockwell Hardness Tester
Application:
It is suitable to determine the Rockwell hardness of steel pipe, pressure vessel, drill stem and other cylinder type parts, may determine the Rockwell hardness test of plane type parts also. It is one online working machine, so testing will be much more faster.

Features:
1. Full automatic test force closed loop control system, test force is stable and reliable.
2. Automatic hardness display, no need for human operation.
3. It can finish the process of clamping, milling, loading, unloading and hardness measuring of workpiece automatically.
4. Precise positioning device for workpiece which can realize the accurate positioning of test point.
5. The milling depth is uniform.
6. The upper and lower limits of hardness are preset in software. It can differentiate whether the test point is eligible or not. It also has the function of alarm in sound and light.
7. Test data can be saved in database for query at anytime.
8. The testing conditions can be preset (including testing material type, workpiece name, date, operator name, etc.).
9. There are many sensors built in whole on-line testing process which can finish the movement of workpiece and hardness testing automatically, no need for human operation.
