Grindosonic Mk7 Impulse excitation tester

Non-destructive measurements of sample resonant frequencies to allow for the determination of Youngs Modulus. Furnace allows testing at temperature up to 1500C.

Non-destructive measurements of elastic properties of materials, Extremely rapid and simple: just a light tap is needed and the result is displayed within a fraction of a second. Measurements of E- and G-modulus and Poisson’s ratio. An alternative to destructive testing as excellent correlations exist between breaking load and natural frequency. Options: Frequency analysis, FFT calculation for detections of multiple vibrations modes, Selection of zones of interest by waveband filtering, Oscilloscope function for time domain analysis, Graphic visualisation of frequency domain.
