200HR-150A optimizes the mechanical structure based on the traditional Rockell hardness meter to improve the stability of the equipment; expands the measurement range; upgrades the shape to meet the modern aesthetic, simplifies the packaging fixation, and facilitates the user installation.

1. 200HR-150A  Rockwell hardness testers adopt mechanical manual test, without power supply, wide application range, easy operation, good economy and practicality.

2. The machine body is integral casting by high quality cast iron, with the automotive paint treatment process, the appearance is round and beautiful.

3. Read the hardness values directly from the dial, and it can be matched with other scales of Rockwell, such as: HRD, HRF etc.

4. Adopt the Friction-Free spindle, high test accuracy.

5. Adopt the precision hydraulic buffer with integral casting, no buffer leakage.

6. loading is smooth, no impact, and the speed is adjustable.

7. The accuracy is in line with GB/T230.2-2018, ISO6508-2 and American ASTM E18 standard.
