2839-2842 NPT 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.

Fields of Application:
  • Water Treatment and Water Quality Monitoring
  • Reverse Osmosis
  • Deionization
  • Cooling Tower and Boiler Protection
  • Distillation
  • Desalination
  • Demineralization
  • Semiconductor
  • Aquatic Animal Life Support Systems
Standards:
  • RoHS compliant
  • China RoHS
Advantages:
  • ±2% accuracy - Custom calibration certificate provided
  • Dual-threaded
  • Compact electrode length for easy in-line installation in small pipe sizes
  • Triple orifice flow-through design reduces clogging and bubble entrapment
  • 316 SS electrodes with injection-molded PVDF process connections and insulators
  • Meets USP requirements
