The new Indentron series of Rockwell hardness testing systems from Ametek Test & Calibration Instruments, features a unique cantilevered load arm configuration that provides an exceptional view of the indenter and test location. The cantilevered design enables the use of only one bearing, ensuring virtually friction-free and maintenance-free operation. This innovative design makes the Indentron ideal for testing inside diameters and recesses that are often impossible to test using standard indenters.
The cantilevered design eliminates frictional inconsistencies that are typical of competitive testing systems. It also ensures accurate test positioning, which prolongs diamond life and enables international diameter testing as well as other tough to measure locations such as shoulders, recesses and grooves.
The Indentron is able to test inside diameters as small as 1.5in with a standard indenter and as small as 0.5in with optional indenters. The tester’s use of precision dead weights for both major load and preload ensures accurate and repeatable measurements by reducing errors that may occur due to worn or improperly adjusted springs or load cells.
