The d₃₃ meter is a special instrument for directly measuring the piezoelectric constant d₃₃ values of piezoelectric ceramics and single crystals. This meter can also measure the d₃₃ values in various single crystal directions for crystals such as lithium niobate, quartz and tourmaline. It is also capable of measuring the d₃₃ value over a very large range, at high resolution and with a high degree of reliability. The measurement is quick and easily made with a minimum amount of training required. Specimens of a variety of sizes and shapes can easily be accommodated and measured. For example the d₃₃ value of discs, blocks, rings, tubes and semispherical shells can be measured using the d₃₃ meter. The direct d₃₃ value readout is displayed on a 2.2 inch digital display. This instrument is invaluable as a tool for quality assurance of piezoelectric materials, production in-line inspection and for research applications.
