KHRS-150/45DX touch screen digital dual Rockwell hardness tester

KHRS-150/45DX touch screen digital dual Rockwell hardness testerIt is a new generation of high-tech intelligent product, adopting a closed-loop loading control system, with high precision of test force, good repeatability and stability of indication. The shell is cast in one piece and treated with automotive paint on the surface, with a novel shape and good reliability, operability, and repeatability. It also has complete functions and clear and intuitive display. By using automatic loading and unloading test force, hardness testing of the entire series of Rockwell scales can be carried out. The measuring device adopts a grating sensor, and the hardness reading is directly displayed on the LCD screen. Capable of automatically converting various hardness parameters to each other. When testing a cylinder, a correction amount can be automatically added. Built in printer to read relevant test results. Automated operation has been achieved, eliminating human operation and reading errors. At the same time, the machine is also equipped with an emergency stop device for safer use.

KHRS-150/45DX touch screen digital dual Rockwell hardness testerMain functions and features of the instrument

1. The 8-inch LCD touch screen can intuitively display hardness values, convert hardness, test methods, test force, brightness, initial test force holding time, total test force holding time, elastic recovery time, measurement times, statistical data, testing time, etc;

2. The system comes with a calibration function that can automatically adjust the error range to 80-120%, or calibrate the instrument separately for low and high values;

3. When testing surfaces, automatically adjust according to the standard surface radius;

4. Can store 100 sets of test data, view test data at any time, delete current data or clear all test data;

5. The test force units can be converted to each other, and the conversion units are: (Kgf, N)

6. Can simultaneously display: average value, number of tests, product name;

7. The main interface can display 4 conversion scales at the same time and can switch between: National Standard (GB), American Standard (ASTM), and International Standard (ISO), with a total of 20 measurement scales that can be converted: HRA、HRB、HRC、HRD、HRE、HRF、HRG、HRK、HR15N、HR30N、HR45N、HR15T、HR30T、HR45T、HK、HBW、HS、HBS、HV、Rm（ Tensile strength)

8. Can set screen sleep time and automatically enter sleep mode if not operated for a long time, saving environmental protection;

9. The upper and lower limits of the measurement range can be set and displayed on the main measurement interface. The unqualified value will automatically prompt an alarm;

10. The operating system has 14 languages, which can be switched at will: Chinese, Chinese Traditional, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, Vietnamese;

11. Configure a built-in printer, and test data can also be output to a USB flash drive for storage and analysis;

12. The cast shell is molded in one go, with a stable and deformation free structure. The pure white car paint has a high grade and strong scratch resistance, and it remains shiny and new even after many years of use;

13. The machine provides lifelong replacement of parts and maintenance upgrade services;

Main purpose and scope of use of the instrument:

1. Determination of Rockwell hardness of ferrous metals, non-ferrous metals, and hard alloys:

2. Rockwell hardness of castings, annealed steel, normalized steel, non-ferrous metals, and soft alloys;

3. Rockwell hardness of heat treated materials such as quenching and tempering;
