Fact vs Fiction
King Pin Tester®
Fiction: King Pins™ are not standard to the HB scale.
Fact: King Pins™ come with a reference sheet to the HB scale.
Fiction: I am not strong enough to operate the King Pin Tester® hammer.
Fact: The King Pin Tester® hammer is very easy to operate and operator strength is not a factor for an accurate reading.
ePortaRock:
Fiction: The ePortaRock L and ePortaRock 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: I cannot have a ePortaRock L or ePortaRock H because I cannot have Bluetooth technology in my workplace
Fact: While the new ePortaRock L and ePortaRock H are Bluetooth, there is another model that does not utilize Bluetooth.
Fiction: There is no way a tester as small as the ePortaRock L and ePortaRock H can have the same accuracy as a bench tester.
Fact: This might be true in some cases, but the ePortaRock L and ePortaRock H are designed and built to deliver a test that has the same accuracy as a bench unit.
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 ePortaRock L and ePortaRock H are superior units with a spring load cell, which is the most accurate and durable load application.
Fiction: The ePortaRock L and ePortaRock H do not meet the standard because they are unable to deliver a 100kg load.
Fact: The ePortaRock H delivers a 100kg load. The ePortaRock H carries load requirements for all Rockwell scales lower than Rockwell C. The ePortaRock L is designed to deliver a 5kg load to accommodate softer metals.
CaseRock:
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.
