2. Implementing new national and international standards:

GB/T231.2 "Metallic Brinell Hardness Test Part 2: Verification of Hardness Testers" International Standard ISO6506.2

“Metallic Materials-Brinell Hardness Test-Part2:Verification and Calibration of Testing Machine”

ASTM E-10 "Test Method for Brinell Hardness of Metallic Materials"

3. HB-3000H electronic Brinell hardness tester (raised type) - Product features:

• The testing space has been increased, with a vertical space of 430mm and a throat depth of 200mm, making it particularly suitable for measuring medium and large parts.
• By adopting a precision mechanical structure and a microcomputer closed-loop control system, the traditional weight loading is eliminated, and the test force during the testing process is automatically controlled.
• The experimental process is fully automated, and the loading, holding, and unloading of the test force are accurately controlled by a microcomputer, ensuring accuracy and reliability.
• Provide 10 levels of testing force, and the selection and switching of testing force can be easily completed by pressing the button.
• High brightness, large screen LCD display, accurately set and display test parameters, including test force, holding time, type of indenter, operation prompts, and other information.
• Due to the removal of weights, the overall weight of the machine has been reduced by 50% compared to a regular Brinell hardness tester.
• No longer need to manually move weights, greatly reducing the labor intensity of operators, eliminating hidden dangers, and improving labor efficiency.
• Read the indentation diameter with a 20X reading microscope.
• Create a hardness calculator function that automatically calculates hardness values, eliminating the inconvenience and error prone defects of checking tables.
