Hydrostatic piezoelectric constant tester (dₕ tester) is used to measure the piezoelectric constant dₕ of under hydrostatic pressing conditions. In addition, by connecting an external impedance analyzer, it can also test the changing trends of constants such as the dielectric properties of piezoelectric samples with the variation of hydrostatic pressure.
| Models | Hydrostatic pressure rang | Dimensions of high pressure tank | Pressure holding timing duration | Charge test range | Time constant of charge amplifier | (Manuals) |
| DH1000 | 5~100MPa (Customizable) | 100mm((Diameter)*150mm(Height) (Customizable) | >1h | 100~5×106pC | >10000 seconds |
