Digital instrument for measuring the longitudinal, torsional and flexional resonance frequency; with a 7" touch screen monitor, battery pack and integrated battery management
The Digital Resonance Frequency Tester calculates the frequency of the longitudinal, torsional and flexional resonance on concrete or natural stone samples in order to determine the Modulus of Elasticity, the damping factor and to analyse the deterioration caused by the freeze-thaw cycles of the material being examined.
The instrument is provided with an embedded PC and colour LCD monitor with integrated 7" touch-screen. The USB interface on the front panel ensures quick and safe management of acquired data.
The user is guided through the entire measurement process in a simple and intuitive way, with explanatory illustrations.
The unit is provided with software, which allows management and organisation of the measurements and the creation of test reports.
