Signet 2818-2823 Conductivity/Resistivity Electrodes are designed to provide versatile installation and accurate sensing across a very broad dynamic range. These electrodes are built with a controlled surface finish to ensure accuracy and repeatability. The standard electrode is constructed of 316SS, but there are other materials available for maximum chemical compatibility.
Reversible threads or sanitary flanges allow for maximum installation versatility. Sanitary flange versions are available in stainless steel and Titanium with surface quality finish of less than RA 25 and with an optional NIST traceability certificate to meet USP requirements.
