Features & Benefits:

  • Conforms to ASTM C-215 and C-666.

  • The only method of calculating the following material parameters non destructively:
    -Youngs Modulus of Elasticity,
    -Modulus of Rigidity,
    -Poissons Ratio,
    -Damping Constant.

  • Available for specimen sizes up to 6 inches (150mm) cross section dimension and from 1.75 inches (45mm) to 28 inches (700mm) in length.

  • Automatic identification of the resonance frequency. Large easy to view display for data analysis of time domain and frequency spectrum signals.

  • Data can be stored and uploaded to a PC for further analysis and inclusion in reports.

  • Fast and easy to use system.

Principle
The principle used in the E-Meter Mk II™ is based upon the determination of the fundamental resonant frequency of vibration of a specimen generated by an impact and sensed by an accelerometer. The frequency spectrum is computed and displayed by the meter.

For the determination of the resonant frequency of materials. The E-Meter Mk II™ measures the resonant frequencies of the three different modes of vibration – Longitudinal, transverse (Flexural) and torsional.

From these the following material characteristics can be calculated –
-Young’s Modulus of Elasticity,
-Modulus of Rigidity and
-Poisson’s Ratio.
