The Emodumeter™ measures the resonant frequency of concrete and other materials for determinations of Young’s modulus, modulus of rigidity and Poisson’s ratio. This device is used extensively in the lab for nondestructive analyses of concrete freeze-thaw samples. An impact using a hardened steel ball is sensed by an accelerometer, then measured and displayed by the Emodumeter ™. The frequency spectrum is computed and displayed by the meter. Three different modes of vibration are measured; longitudinal, transverse (flexural), and torsional.

Samples with cross-section up to 6in (150mm) length from 1.75 inches (45mm) to 28 inches (700mm) in length can be tested. Frequency range is 10Hz to 40kHz, with 4.9 to 78.1Hz resolution. Maximum amplitude is automatically calculated, eliminating cumbersome frequency scanning. Time domain and frequency spectrum results for 200 tests can be stored and uploaded to a PC for further analysis.

The system includes the Emodumeter™ in an integral sturdy plastic carrying case, accelerometer with pick-up cable, set of six hardened steel balls, universal charger, RS-232 cable, software, and specimen bench fixture. Emodulinx software is also included, and allows to user to export data to a PC for management and analysis. The charger includes a universal plug adaptor and operates on 110 to 240V/47 to 63Hz. 12V rechargeable battery allows 4 to 10 hours of continuous use.
