Product Description
+GF+ 3-2850-52-39 - Ultra-Pure-Water-Conductivity-Detect/4-20mA-Analog-Transmit - PVDF K=0.01 3/4"NPT PT1000 Resistivity Conductivity Electrode
Toroidal Conductivity System Overview

The 3‑2850‑52‑39 system pairs 2850 smart electronics with a 2839 toroidal (electrodeless) sensor for high-conductivity and fouling media applications. This system outputs Digital (S³L) signals to compatible devices including 8850/8860/8900/9900 series instruments, making it ideal for applications where contacting cells would typically foul.

Industrial Applications

This system provides drift-free conductivity measurements for demanding applications including:

  • Brine tanks and concentration monitoring
  • Sludge and pulp processing
  • Chemical slurry applications

The electrodeless design eliminates reference junction poisoning concerns. With minimal maintenance requirements, this system excels in harsh 24/7 process loops. The -39V PVDF version provides enhanced chemical resistance for aggressive chemical environments.
