Resonance Frequency Meter
The Resonance Frequency Meter is used for determining the Longitudinal, Transverse (Flexural) and Torsional resonant frequency of concrete and natural stone samples.
How it works
The resonant frequency allows for the determination of the Dynamic Modulus of Elasticity and the Dumping coefficient analysis frequently used, for instance, to determine the degradation due to freezing and thawing cycles.
The 58-E0035/D meter is provided with PC embedded board and colour LCD monitor with integrated 7″ touch-screen that guides the operator through a user-friendly test procedure with relevant prompts.
RES-Reader software
The Resonance Frequency Meter comes supplied complete with the RES-Reader software which allows the management of data with a PC and the production of test reports.
