E-Meter MKII™
Determine resonant frequencies

For the determination of the resonant frequency of materials.

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.

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.

System
The E-Meter™ MK II has an automatic feature that computes the aximum amplitude, which eliminates cumbersome frequency scanning. Frequencies are automatically shown in the display and a cursor allows the user to move along the frequency spectrum. Also the time domain signal and the frequency spectrum can be stored and uploaded to a PC for further analysis and inclusion in reports.

Resonance Frequency
The E-Meter™ MK II performs a Fast Fourier Transform that allows the identification of the resonance frequency in the Frequency Spectrum.

Durability of Concrete
The determination of flexural resonance is very important when studying the degradation of concrete under accelerated freezing and thawing cycles and aggressive environments on concrete specimens.
The advantage of resonance methods are:

Tests can be repeated over a very long period on the same specimen; the number of test specimens required is therefore greatly reduced.
The results obtained with the resonance method on the same specimen are more reproducible than those obtained with destructive tests and groups of specimens.
