How a Field Hardness Tester Works

Basic Working Principle

A field hardness tester evaluates resistance of a material to deformation by applying impact or ultrasonic vibration.

Rebound Method

Measures rebound speed after impact on a metal surface.

Ultrasonic Method

Uses frequency change in a vibrating probe to determine hardness.

Both methods are widely used in modern field hardness tester systems.
