Johoyd CHRTS-150ZS Rockwell Hardness Tester (15kgf~150kgf)

Main functions and characteristics of the instrument:

1. The 8-inch LCD touch screen can directly display the hardness value, converted hardness, test method, test force, brightness, holding time of initial test force, holding time of total test force, elastic recovery time, measurement times, statistical data, test time, etc

2. The system has its own calibration function, which can automatically adjust the error range of 80-120%, or calibrate the instrument separately for low and high values

3. When testing the surface, it is automatically corrected according to the standard surface radius;

4. It can store 100 groups 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 unit is: (Kgf, N)

6. It can display the average value, test times and product name at the same time;

7. The main interface can display 4 conversion scales at the same time and can switch: national standards (GB), American standards (ASTM) and international standards (ISO). A total of 20 measurement scales 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. It can set the screen sleep time, and automatically enter the sleep state without operation for a long time, saving environmental protection;

9. The upper and lower limits of measurement range can be set, which is displayed on the main measurement interface, and the unqualified value will automatically prompt the 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. Equipped with built-in printer, test data can also be output to USB flash disk for saving and analysis;

12. The one-time forming structure of the casting shell is stable and does not deform. The pure white car baking paint is of high grade and has strong scratch resistance. It is still as bright as new after years of use;

13. Our company has the ability of self-development, design and production. Our machines provide life-long service of parts replacement, maintenance and upgrading;

Main purpose and scope of use of the instrument：

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

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

3. Rockwell hardness of quenched, quenched and tempered and other heat treated materials;
