描述了一种用于测量固体和熔融聚合物从室温到250 ℃的电导率的装置。通过将热源和样品封闭在散热器内来消除“边缘效应”，因此不使用保护环。热流是三维的，通过数值计算得到的传导率。需要两个直径为48 mm、厚度为2 mm的圆盘形样品。给出了一些典型结果。
An apparatus for measuring the conductivity of solid and molten polymers from room temperature to 250 degrees C is described. 'Edge effects' are eliminated by enclosing the heat source and samples inside the heat sink, hence guard rings are not used. The heat flow is three dimensional and the conductivity is obtained by a numerical calculation. Two disc shaped samples 48 mm diameter by 2 mm thick are required. Some typical results are given.
