Brief Introduction
● The Digital Rockwell Hardness Tester is equipped with a newly-designed large displaying screen and the menu structure equipped operation panel with good reliability, excellent operation and easy watching. The typical feature of present hardness tester is to test the hardness value reliably and accurately. The errors of hardness values can be revised by pressing input keys; therefore, it enables the hardness values measured more precisely to meet the needs of test requirements.
● Here are the major functions:
● The selection of Rockwell Hardness Scales:HRA,HRB,HRC,HRD,HRE,HRF, HRG,HRH,HRK,HRL,HRM,HRR,HRP,HRS,HRV
● The selection of plastic Rockwell hardness scale (the special requirements will be met according to the supply contract);
● The change and substitution among various hardness systems;
● The out printing and output of hardness testing results;
● RS-232 hyper terminal setting for the functional expansion by the client.
● The errors of hardness values can be revised by pressing input keys; therefore, it enables the hardness values measured more precisely to meet the needs of test requirements.
● Standard: GB/T230.2, ISO6508-2 , ASTM E18
