The resonant frequency permit the determination of the Dynamic Modulus of Elasticity and the Dumping coefficient analysis frequently used, for distance, to determine the degradation due to freezing and thawing cycles.

The meter is provided with PC embedded board and colour LCD monitor with integrated 7" touch-screen.  

Used for determining the Longitudinal, Transverse (Flexural) and Torsional resonant frequency of concrete and natural stone samples.

User friendly test procedure with relevant displays.

Supplied complete with software which allows the management of data with a PC and the production of test reports.
