This electrode consists of two platinum black plated platinum sheets (platinum black electrode), with an electrode constant in the range of 0.80 to 1.20. The electrode head of the conductivity electrode is easily damaged. When measuring, be careful not to collide with the container to avoid damage. When measuring solutions with very low conductivity, use containers made of neutral glass, quartz, or plastic with low solubility. To prevent the platinum black electrode from becoming inert during use, it must be immersed in distilled water before and after use. Once the platinum black electrode is found to be inert, rinse it with distilled water or reconfigure the platinum black electrode.
