1、 Product Introduction:

ZJ-3Type piezoelectric tester (static pressure coefficient)d33The measuring instrument is used to measure piezoelectric materialsd33A specialized instrument designed for constants, which can be used to measure piezoelectric ceramics with large piezoelectric constants, piezoelectric single crystals with small piezoelectric constants, and piezoelectric polymer materials. In addition, it can also measure the equivalent piezoelectric properties of piezoelectric single crystals with arbitrary orientations and certain piezoelectric devicesd’33Constant, wide measurement range of the instrument, fine resolution, high reliability, simple operation, no special requirements for sample size and shape. It can measure circular discs, rings, tubes, blocks, strips, columns, and hemispherical shells. The measurement results and polarity are directly displayed on a three and a half digit panel table.ZJ-3The model has added functions such as discharge protection, discharge prompt, and waveform output for the tested components, enabling the instrument to provide high-voltage discharge prompt and protection when measuring non discharged (especially large-sized) piezoelectric components. This instrument is used in the production, application, and research departments of piezoelectric materials and piezoelectric components.

2、 Main application areas: non-destructive testing ultrasonic testing, medical ultrasonic testing, aerospace, oil and gas equipment, automotive IoT, industry, consumer programs, etc.
