Specifications and Features
2839-2842 NPT Conductivity-Resistivity Electrodes
The Signet 2839-2842 Conductivity/Resistivity Electrodes are available in four cell constants from 0.01 to 10.0 cm-1, and are suitable for a wide variety of applications from high purity water quality monitoring to weak acids and bases. 316 Stainless Steel electrode surface finishes are controlled in a precision bead-blasting operation to ensure measurement accuracy and repeatability.
The PEEK™ insulator and process connections are injection over-molded to minimize variance between electrodes. Double threaded connections in either ¾ in. NPT or ISO 7/1-R 3/4 enable quick and easy installation in submersible or in-line configurations. Transmitter integral mounting kits and junction boxes are available as accessories.
A Certificate of Calibration is included with all 2839-2842 Conductivity Electrodes. The electrodes are calibrated to meet 1% accuracy. Electrodes can be shipped back to the Signet Factory for recertification.
