It is primarily used for measuring the bulk ionic conductivity (perpendicular to the membrane plane) of solid electrolyte membranes such as proton-exchange membranes and ion-exchange membranes, and can also be employed for rapid measurement of the bulk resistivity or conductivity of conventional insulating or conductive thin films. The fixture is made of stainless steel and PEEK, offering resistance to acids, alkalis, and high temperatures; its electrode leads are positioned on the top of the fixture, enabling in-situ testing in electrolyte solutions (with the fixture placed inside a beaker) or under high‑temperature, high‑humidity conditions. During the clamping process, the metal electrodes move only vertically—without rotating—to prevent damage to the membrane. The operation is straightforward: after cutting the membrane to size, place it in the fixture, tighten the knob to ensure proper contact, or use a torque wrench for precise pressure control, then measure the membrane’s conductivity using the AC impedance spectroscopy (EIS) method.
