HRS-150 digital automatic Rockwell hardness tester has a novel appearance, a menu-based interface, the measuring device is controlled by a grating sensor and a computer, and the hardness display value is directly displayed on the LCD screen.
The function can automatically convert various hardness parameters to each other, identify the minimum thickness of the test piece and determine the ambient temperature of the test. Built-in printer to read relevant test results. Automated operation is achieved, eliminating human operation and reading errors.
1. Main functions and features:
1. Directly display the test hardness value through the large LCD screen.
2. The shell is cast by a special sand casting process, the structure is stable and not deformed, and it can work in a relatively harsh environment; the car paint is of high grade, with strong scratch resistance, and it is still bright as new after many years of use;
3. The machine provides parts replacement and maintenance upgrade services for life.
2. Main purpose and scope of application:
Cast and forged parts, sample testing and acceptance inspection, flat and cylindrical workpieces, steel, non-ferrous metals, automotive and aerospace, carbide, ceramics, stainless steel, laboratories and workshops.
