เครื่องทดสอบความแข็งแบบตั้งโต๊ะชนิด Rockwell TB-R-C (NOVOTEST)

Digital Rockwell Hardness Tester NOVOTEST TB-R-C

Digital Rockwell hardness tester TB-R-C implements direct Rockwell method of hardness testing in accordance with ISO 6508-2 and ASTM E18.

Application

Rockwell Hardness Tester NOVOTEST TB-R-C allows user to measure hardness of:

• hardened and surface hardened steel, hardened and tempered steel;
• cold and hard casted parts, forged parts;
• hard alloy steel;
• aluminium alloys;
• bearing steel;
• carbonized steel sheets and others.

Digital model has following advantages against analog machine:

• more convenient in operating;
• measurement process is faster;
• setting menu is easy in use (setting of scales, loads and dwell time etc.);
• digital resolution is better. As a result, accuracy is higher than manual tester has;
• RS-232 interface;
• human factor influence is minimum.

The machine allows user to:

• select the Rockwell hardness scales type (A, B, C, D, E, F, G, H, K);
• recalculate the obtained hardness values into all hardness scales (Brinell, Rockwell and Vickers);
• record test results under the particular operator;
• print the results of hardness measurements via built-in printer;
• automated load/unload system allows user to get measurement results of high accuracy and free of operator faults.
