Application Range:

The micro hardness testing of materials allows for the determination of the hardness of small or thin specimens and small areas of larger specimens, Micro hardness testing is commonly used to determine characteristics of thin sheets, foils, fine wire, epoxies, paints, etc. and is often employed in R&D applications.

Micro hardness is especially useful in determining hardness variations, caused by hardening, quenching, plating, fabrication, welding or annealing, bonding, etc. Micro hardness testing can be accurately employed using loads as slight as 10 grams, somewhat less and considerably more in certain situation.

Optional Vickers hardness testing software is available for CDH (Carburized layer depth) measurement.
