General description
General description
Used for determining the Longitudinal, Transverse (Flexural) and Torsional resonant frequency of concrete and natural stone samples.
The reasonant frequency permit the determination of the Dynamic Modulus of Elasticity and the Dumping coefficient analysis frequently used, for istance, to determine the degradation due to freezing and thawing cycles.
The 58-E0035/C meter incorporate a PC card and a color touch screen 7" monitor. 
User friendly test procedure with relevant displays.
Supplied complete with RES-Lab software which allows the management of data with a PC and the production of test reports.
