Signet 2818-2823

The Signet 2818-2823 Conductivity / Resistivity Electrode range 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 316 SS or Titanium, 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 with surface quality finish of less than RA 25 and with an optional NIST Traceability Certificate to meet USP requirements. Coupled with Signet patented measuring circuitry, a three-decade measurement range is achieved without the need for troublesome electrode platinization. A platinum RTD (PT1000) located within the electrode allows optimal temperature sensing.

Features of the Signet Conductivity Electrodes include:

• Controlled surface finish ensures accuracy and repeatability.
• Flow-through design
• In-line or submersible installation
• Accuracy ±2% of cell constant (certified cells ±1%)
• Range of standard process connections
• Standard electrode in 316SS or titanium, with other materials available for maximum chemical compatibility
• Standard wiring allows connection without costly “patch cords”.
