2839-1V(D)-2842-1V(D) PVDF Conductivity-Resistivity Electrodes


The Signet 2839-1V(D) to 2842-1V(D) 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 SS electrode surface finishes are controlled in a precision bead blasting operation to ensure measurement accuracy and repeatability.

The PVDF 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 kit and junction boxes are available as accessories.

A Certificate of Calibration is included with all 28391-V(D) to 2842-1V(D) Conductivity/Resistivity Electrodes. The electrodes are calibrated to meet
± 2% accuracy. Electrodes can be shipped back to the GF Signet factory for recertification.
