The GF Signet 2881-2884 conductivity/resistivity electrodes are available in four cell constants from 0.01 to 10 cm⁻¹, covering applications from high purity water monitoring to chemical process solutions. The 0.01 and 0.1 cm⁻¹ versions are ideal for ultrapure water and USP purified water, while the 1.0 and 10.0 cm⁻¹ versions suit higher conductivity solutions.

Electrodes are constructed with 316L stainless steel sensing elements and an integral Pt1000 RTD for accurate temperature compensation. Standard accuracy is ±2%, with optional ±1% NIST-traceable certification available. Dual-threaded process connections (3/4" NPT or ISO 7/1-R 3/4) allow inline, immersion, or integrated mounting with Signet transmitters.

Models 2881, 2882, and 2883 feature coaxial electrode design with PEEK insulators and a 316L thermowell. Process connection materials include polypropylene, CPVC, PVDF, or PEEK. Model 2884 features parallel electrode design with PTFE insulators, 316L thermowell, and CPVC housing and process connection.

The triple flow-through vent hole design ensures accurate measurement by eliminating trapped air. Each unit includes 25 feet (7.6 m) of integral cable. Applications include pure water treatment (RO, DI, distillation), boiler condensate, semiconductor water production, USP purified water, and rinse water monitoring in coating, cooling towers, and desalination systems.
