E-Meter

The E-Meter determines the flexural resonance of concrete under accelerated freezing and thawing cycles and aggressive environments.  It finds the resonant frequencies of the three modes of vibration and is the only method of calculating the following material parameters non-destructively.  The frequencies automatically scan in one of four ranges.  It can handle specimen sizes up to 6 inches in cross section and 1.75″ – 28″ in length.  A semi-automatic feature facilitates the fast identification of resonance.

• Frequency Indicator Display:  6 Digit LED
• Gate Times:  1 second or 10-second switch selected, LED indicated
• Accuracy:  20 ppm + 1 count over full operating temperature range
