1) Electronic electric loading, high precision sensors, with a unique closed loop control system. 2) With the touch screen interface, the operator can directly select the hardness scale, and the force value can be changed automatically in the test parameters. 3) According to the standard hardness block, each hardness scale is divided into high, middle and low sections for automatic correction. 4) The test force can be automatically corrected by standard dynamometer. 5) Automatically apply the initial test force and the main test force. 6) Powerful data processing function, including: HR, HB, HV and other hardness system conversion, set the qualified range, automatic alarm over the limit, can input the tester, sample name and other information. 7) More sample and test information, measurement data USB disk saved in EXCEL format, easy to edit and process. Initial test force 3.0KGF (29.4N) Main test force 15kgf(147.1N) 30kgf(294.2N) 45kgf(441.3N) Hardness scale 15N、15TW、15W、15X、15Y、30N、30TW、30W、30X、30Y、45N、45TW、45W、45X、45Y Rockwell test range HR15N:70-94 HR30N:42-86 HR45N:20-77 HR15TW:67-93 HR30TW:29-82 HR45TW:10-72 Meet standard BSEN 6508, ISO 6508, ASTM E18, GB/T230 Dwell time 0-99s Hardness resolution 0.1 HR Error of test force < 1% Data output LCD display Data is stored The measured values are saved on USB flash drive in Excel format Conversion scale Rockwell, Brinell and Vickers Maximum allowable specimen height 200mm
