Máy đo độ cứng Rockwell THR-45D

Digital Rockwell hardness tester

Main Features:

THR-45D Digital Rockwell hardness tester is equipped big screen

LCD monitor. Operation panel use the menu type structure, the main functions are: Rockwell hardness of

the scale choice, the choice of plastic Rockwell ruler, various guide the conversion between hardness,

hardness testing results automatically save and RS-232 super terminal Settings, hardness value error can

be modified through software input, hardness value more accurately meet test requirement.
