1.INTRODUCTIONThe Model YE2730 d33 meter is a special instrument for directly measuring the piezoelectric constant d33 values of piezoelectric ceramics,Website:http://www.china-yec.net, polymers, 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. This meter is capable for 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 of training required. Specimens of a variety of sizes and shapes can easily be accommodated and measured. For example, the d33 value of disks, blocks, rings, tubes and semispherical shells can be easily measured on the Model YE2730 d33 meter. The direct d33 value readout is displayed on a 3 1/2 inch digital meter. This instrument is invaluable as a tool for quality assurance of piezoelectric materials, production in-line inspection, or for research applications.Features of D33 test meter:measure d33 values from 1 to 2000 pC/Nfast, accurate, direct readout (3.5& quot; / 9 cm display)high resolutionhigh repeatabilityno technical expertise needed -- easy training / easy to operateaccommodates varied size / shape ceramic elements, single crystalslow costcomplete and ready to use for measuring d33 values, determining polaritystable reference sample for calibrating the d33 meter included2.SPECIFICATIONS:
