01System Introduction

02. Testing Method

Using the parallel plate capacitance method, place the sample on a precisely temperature controlled sample stage with ceramic silver plates placed on it. One probe contacts the upper electrode of the sample, while the other probe contacts the silver layer of the ceramic silver plate, thereby conducting with the lower electrode of the sample and measuring the sample capacitance. Before testing, it is necessary to measure the sample size and input it into the software, so that the dielectric constant of the sample can be automatically calculated at different temperatures.

03. Test results
