Knoop Indenter

Is a Cone-Shaped Diamond Indenter for IQUALITROL Micro Hardness Testers

Main Features:

Apyramid shaped diamond is used for testing in the Knoop scale. This indenter differs from the 1pyramid indenter used on a Vickers test.

The Knoop indenter is more elongated or rectangular in shape. The Knoop method is commonly used when indentations are closely spaced or very near the edge of the sample.

The width of the Knoop indentation can provide more resolution for measurement and the indentation is also less deep. Consequently, it can be used on very thin materials.

In a Knoop test, a predetermined test force is applied with apyramid-shaped diamond indenter for a specified dwell time period.

Various diamond indenters, tungsten carbide ball indenters and steel ball indenters are suitable for all types of iqualitrol hardness testers; indenters of various special specifications and sizes can be customized made.
