The DR-HRS-150 digital automatic Rockwell hardness tester features a novel appearance and a menu-based interface. The measurement device employs a grating sensor and computer control, and the hardness value is directly displayed on the LCD screen. It is an integrated mechanical and electrical hardness testing instrument.
This machine can automatically convert various hardness parameters, identify the minimum thickness of the
test piece and measure the ambient temperature of the test. It is equipped with an internal printer to read the relevant test results. It realizes automated operation, eliminating human operation and reading errors.
Main functions and features:
1.The test hardness value is directly displayed on the large LCD screen.
2. The shell is cast in one piece by a special sand casting process, with a stable structure that does not deform, allowing it to operate in relatively harsh environments. The automotive paint is of high grade, with strong scratch resistance, and remains as bright as new even after years of use.
3. We have the capability to independently research and develop, design, and produce and process. We offer lifetime services for parts replacement, maintenance, and upgrade for the machines.
Main uses and application scope:
Casting and forging parts · Sample testing and acceptance inspection
Flat and cylindrical workpieces · Steel, non-ferrous metals
Automotive and aviation industries · Hard alloys, ceramics, stainless steel laboratories and workshops
