Portable Rockwell Hardness Tester

Features

Miniaturization of Rockwell hardness tester, the smallest model weighs only 0.8kg and the operation is similar to that of a micrometer.

The testing principle and accuracy comply with ISO 6508 and ASTM E110, tested by National Institute of Metrology with error less than 1.5HRC, same as the bench type.

The instrument is composed of tester and bench stand, can be used on table or on site in the factory.

Can test many kinds of thin, small, long and irregular parts that cannot be tested by the bench type.

Well suits for testing the workpieces with small supporting surface.

Traceable standard hardness block.

Indenter inspected with standard Rockwell hardness tester.

Test force calibrated with load cells directly traceable to national

secondary benchmark.
