+GF+ 3-2840-1 - Water-Conductivity-Measure/PT1000-Temp-Compensate - PVDF 316SS K=0.1 Threaded Industrial Conductivity Resistivity Electrode
The 3‑2840‑1 is a K=0.1 cm⁻¹ conductivity/resistivity electrode covering 1 - 1,000 µS/cm (~0.5-500 ppm TDS), with 316SS electrodes, PP insulator, PT1000 ATC, and ¾″ NPT 316SS process connection on a 4.6 m shielded cable. Accuracy ±2% of reading, mates to 2850 electronics → 8850/8860/8900/9900.
Provides temperature-compensated conductivity measurements for RO/DI quality interlocks, boiler condensate, cooling-tower makeup applications where K=0.01 is oversensitive and K=10 saturates. 316SS/PP construction suits general water and light-chemical applications; for aggressive media, upgrade to -1V (PVDF) version. Dual-thread NPT fits tees or standpipes—ideal for audit-friendly mid-purity applications.
