E-Meter MK II - For Determination of the Resonant Frequency of Materials

ASTM C215 & ASTM C666

For the Determination of the Resonant Frequency of Materials

The E-Meter MK II is used to test and determine the resonant frequencies of the three modes of vibration. Material characteristics such as Youngs Modulus of Elasticity, Modulus of Rigidity, Poissons Ratio and the Damping Constant can be calculated. Frequencies are automatically scanned in one of four ranges. The system can determine flexural resonance of concrete under accelerated freezing and thawing cycles and aggressive environments. The unit is designed for laboratory determination of concrete or other material samples as a non-destructive test, allowing you to perform accurate and repeatable tests on fewer samples. The computational system features an automatic computation of the maximum amplitude eliminating the need for cumbersome frequency scanning testing. The E-Meter MKII conforms to ASTM C-215 and C-666.

The E-Meter MK II, in addition to conforming to ASTM C-215 for determining resonant frequency can be adapted for:

ASTM C-623	Glass
ASTM C-747	Carbon and Graphite
ASTM C-848	Ceramic Whiteware
ASTM C-885-78	Refractories
ASTM C-666	Concrete – Freeze Thaw.
