Myths Surrounding Ernst by King Rockwell Testers
Fiction: The CaseRock costs too much.
Fact: The CaseRock is an investment. Effective case depth measurement used to take 45-60 minutes, now the measurement takes one minute and is nondestructive and test pieces do not need to be prepared. The CaseRock drastically increases efficiency and productivity.
PortaRock L and PortaRock H:
Fiction: The PortaRock L and PortaRock H do not adhere to ASTM E-18 standards.
Fact: No portable Rockwell tester adheres to the ASTM E-18 standard but it does adhere to ASTM E-18 indirectly as a Rockwell tester.

Fiction: The Leeb tester is just as good.
Fact: The Leeb does not leave an indentation so there is no reliability or repeatability. The Leeb uses force of a rebound to give a ballpark estimate of the hardness. The PortaRock L and PortaRock H are superior units with a spring load cell, which is the most accurate and durable load application.
Fiction: The PortaRock L and PortaRock H do not meet the standard because they are unable to deliver a 100kg load.
