UltraSonic Hardness Tester

Fowler's new Ultrasonic Hardness Tester works on a principle of vibration to measure hardness electrically and through a sophisticated algorithm, converts the measured signal into a accurate, repetitive measurement.
UltraSonic Tester Features
Compact size for portable use. Direct-reading of hardness by digital display. Very small indentation < 0.001" Conversion between HV and HRC. Works with or without standard base. Multi direction applicability, works in any direction.
