Touch Screen Rockwell Testing Rockwell And Superficial Rockwell Hardness Tester HR-150/45DX
The use and scope of Rockwell hardness tester
Rockwell hardness tester is designed according to the principle of Rockwell hardness test. Its measurement range is: 20 ~ 88HRA; 20 ~ 100 HRB; 20 ~ 70HRC Rockwell hardness value. The hardness tester is manufactured according to the national standard GB2848 ~ 92 "technical conditions of Rockwell hardness tester". It has the advantages of simple structure, stable indicating value and convenient operation and maintenance. It can be used to measure the Rockwell hardness of hard alloy, hardened steel, carburizing steel and malleable cast iron. Widely used in machinery factories, metallurgical plants, colleges and universities, laboratories, etc.
Using range
Rockwell hardness tester test according to the following table to select the pressure head and the total test force:
Total test force N(KGF) of indenter mark hardness symbol allowable measurement range
B Φ1.588/mm steel ball 980.7(100) HRB 20-100
C 120° Diamond 1471(150) HRC 20-70
A 120° Diamond 588.4(60) HRA 20-88
Ruler A: Used for the determination of metals (such as tungsten carbide, cemented carbide, etc.) whose hardness exceeds 70HRC. It can also be used for the determination of hard sheet materials and hardened surface materials.
Ruler C: used to determine the hardness of steel products after overheating treatment.
Ruler B: for the determination of soft or medium hardness metals and unhardened steel products.
(1) Adjust the loading speed of the main test force;
(2) the choice of test force (150KG:1471N 100KG/980.7N 60KG/588N);
(3) carefully install the durometer head.
Main features:
- Adopting electronic and electric loading, high precision sensor, with unique closed loop control system
- Touch screen interface, easy to operate, directly select the hardness scale, the force value is automatically changed in the test parameters
- According to the standard hardness block, the three segments of each hardness scale are automatically corrected.
- The test force can be modified automatically by standard dynamometer.
- Apply the initial test force and the main test force automatically
- The data processing function is powerful, including: HR, HB, HV and other hardness type conversion, setting up the qualified range, automatic alarm for over-limit, and inputting the information such as tester, sample name, etc
- More samples and test information, the measurement data U disk saved in EXCEL format, easy to edit and process
