● 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.

Application

● Small hardness tester is portable at reasonable price, well suits for small parts testing.

● The reliability & repeatability of small hardness testers with 4 inches opening size will be reduced when testing large workpieces, large Rockwell hardness tester is the priority choice in such situation.
