A range of equipment for direct testing of piezoelectric materials and devicesPiezometer System is useful for measuring d33 coefficient of Piezoelectric material.This is also applicable to piezo-ceramics, PVDF polymers, composites and thin film. In this instrument options are available for testing of capacitance, dh coefficient and dielectric loss tan for high-sensitivity testing of low-output materials.Adapters are available for testing of d31 and d15 in the same way.
