Testing Function
Characterizing dielectric response across wide cryogenic-to-high temperature ranges (-160°C to 450°C) is essential for uncovering low-temperature relaxation peaks, ferroelectric-paraelectric phase transitions, and thermal stability in aerospace, automotive, and cryogenic electronic systems. Automated liquid nitrogen cooling combined with precise heating stages enables continuous temperature scanning and multi-frequency impedance acquisition with high signal-to-noise ratio.
