Product Description
The GF Signet 2820 (3-2820) Conductivity/Resistivity Electrode provides efficient installation and accurate sensing across a varied range. The electrode has a controlled surface finish to assure repeatability and accuracy. A variety of construction selections are available such as a 316 SS, titanium or an assortment of other materials for maximum chemical capability. The platinum RTD (PT1000) located within the electrode allows for premium temperature sensing.
More still, when paired with Signet patented measuring circuitry, a three decade measurement range is accomplished eliminating the issues of electrode plasticization.
