Product Description
Model 400HRD-150B Electric Heightened Rockwell Hardness Tester is a semi-automatic Rockwell hardness tester for testing Rockwell hardness of metal materials. The test force application, holding load and unloading are completed automatically, the test process is automated, and there is no human error in operation except for the zeroing of the dial. The change of test force is obtained by rotating the variable load handwheel, which is easy to operate, with high testing efficiency and good stability.
Main features:
cast iron one-time molding body, solid structure, good rigidity, durability, no deformation.
dial direct reading, HRA, HRB, HRC, 3 kinds of Rockwell hardness scale, and optional Rockwell's other scales
accuracy in line with GB/T230.2 ISO 6508-2 and the United States ASTM E18
