+GF+ 3-2745-1 - ORP-Monitor/Signal-Transmit - Sensitive Anti-Corrosion ORP Electrode
Flat Differential ORP Electrode with DryLoc® Connector
The +GF+ Signet 3‑2745‑1 is a flat‑style differential ORP electrode built with a PPS (Ryton) body, PTFE reference junction, and EPDM seal for harsh chemical service. Key specs: –1000 to +2000 mV range, 10K ID temp element, ¾″ NPT, DryLoc® gold‑plated contacts. It feeds 2750/2751 smart electronics and then 4–20 mA or S³L into 9900/8900 controllers.
Where It Works, What It Gains You, and Core Function
Used in plating baths, metal‑finishing effluent, scrubbers, textile dye, and heavy‑metal recovery loops, it delivers a stable redox signal for dosing interlocks and discharge alarms. The differential design + PTFE junction resists poisoning and extends service life, while memory‑chip DryLoc enables auto‑ID/calibration traceability—cutting drift, fouling issues, and maintenance downtime in aggressive, 24/7 processes.
