Description
Features
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 fi nish 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 fl anges allow for maximum installation versatility.
Sanitary fl ange versions are available with an optional NIST Traceability Certifi cate
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.
