Here are the standard accessories in NextGen’s Telebrineller Brinell Hardness Testing System:

The test bar (1), anvil (2), and soft moulded rubber head (3) are all included with the Telebrineller instrument, which is placed on top of the test bar. Non-slip footing is provided by the rubber head and a comparable resting block (4). A steel impression ball (5), fixed in the rubber head’s base, is in contact with the specimen and the test bar beneath it. Sharp blows are made to the anvil with a two to five-pound hammer.

Regardless of force, the impact is equally transferred to the test bar and the specimen metal (6) through the impression ball, leaving impressions in both. The sizes of the impressions that are produced are directly proportional to the specimen’s and the test bar’s relative hardness. The test bar is adjusted to clear space for each test using a spacing bar (7) that is controlled by a spring catch and button.
