Product details
The Signet 2818-2823 Conductivity/Resistivity Electrodes are the perfect choice for accurate and versatile sensing across a broad dynamic range. With a controlled surface finish, these electrodes provide accuracy and repeatability that is unmatched in the industry. The standard electrode is constructed of 316 SS, but other materials are available to provide maximum chemical compatibility.
The reversible threads or sanitary flanges available on these electrodes make them incredibly versatile and easy to install. The sanitary flange versions are available in stainless steel and titanium with a surface quality finish of less than RA 25. Additionally, these versions come with an optional NIST Traceability Certificate to meet USP requirements.
One of the unique features of the Signet 2818-2823 Conductivity/Resistivity Electrodes is their ability to achieve a three-decade measurement range without the need for troublesome electrode platinization. This is made possible by Signet’s patented measuring circuitry. The platinum RTD (Pt1000) located within the electrode allows for optimal temperature sensing, making these electrodes incredibly accurate and reliable.
