Overview:
The fully automatic digital Rockwell hardness tester can automatically measure Rockwell hardness and surface Rockwell hardness. The indenter is horizontally extended and can measure parts such as rings and tubes that cannot be measured by ordinary hardness testers. Multi functional, capable of testing 30 different Rockwell hardness standards, including plastic Rockwell, loading, holding, and unloading, accurately controlled by a computer, suitable for national and ASTM standards, bilingual menu in Chinese and English, large screen, high-definition, and high brightness backlight dot matrix LCD display screen, integrated body casting and molding, using German imported dynamic non-contact sensors, automatically storing 400 sets of measurement data, testing time, and testing serial number, Easy to access or print, with dual communication ports of USB and RS232, and the ability to connect to external printers; Or transfer the test results to the computer.
Main functions:
● Complete measurement scales: capable of measuring Rockwell HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HRL, HRM, HRP, HRR, HRS, HRV, as well as surface Rockwell HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HR15W, HR30W, HR45W, HR15X, HR30X, HR45X, HR15Y, HR30Y, HR45Y, a total of 30 scales. The tested materials cover various hardness ranges, such as hard alloys, quenched steels, alloy steels, soft steels, and copper. Aluminum alloy Engineering plastics, artificial wooden boards, etc.
The unique "protruding nose" structure indenter can test surfaces that cannot be measured by ordinary hardness testers, such as the inner surface of circular, tubular, and frame parts, and the bottom of protruding parts
● Powerful data processing function: Test time, serial number, and test results are automatically stored, and can be accessed and printed at any time without modification or deletion. Effectively monitor testing history to ensure the objectivity and impartiality of historical data.
● Tolerance limit: Set the allowable error limit, automatically recognize and alarm when exceeding the limit.
Data statistics: calculate the mean, mean square deviation, maximum and minimum values, so that uncertainty can be directly evaluated.
● Standard conversion: The test results can be converted into Brinell, Vickers, Leeb, Knoop hardness, and tensile strength.
Curvature correction: Automatically correct the measurement results of curved parts.
Application scope:
Measure the Rockwell hardness of black metals, non-ferrous metals, etc. Quenched steel, quenched and tempered, annealed steel, cold hard castings, malleable castings, aluminum alloys, copper, bearing steel, etc.
