Resonance frequency meter

Digital equipment for the determination of longitudinal, transverse (flexural) and torsional resonance frequencies of samples made of concrete, cement or natural stone. The analysis of resonance frequency enables the determination of the dynamic modulus of elasticity and the attenuation coefficient, which is often used to analyse the degradation caused on materials by the action of freeze-thaw cycles. The equipment includes the digital unit (with case), an application for data management and reports generation, a holding bench for samples, an accelerometer with cable (1 m long), a set of 6 steel balls, and a set of 25 stronghold nuts carrying case for the accessories.
