PTFE junction: Minimizing the potential for clogging and chemically resistant, PTFE is ideal for samples with high content of suspended solids or for high‑pressure installation. Ceramic junction: Porous chemically resistant plug that connects the reference electrode to the process electrically. Platinum sensor: Used in reducing processes such as chlorine dosing in pools and spas or chromate reduction. Gold sensor: Used in oxidative processes such as cyanide oxidation in the mining industry.
