FLXA402 — Yokogawa FLXA402 pH/ORP Analyzer
The Yokogawa FLXA402 pH and ORP Analyzer delivers precise analytical measurement for Saudi Arabia's water treatment, chemical processing, and environmental monitoring applications. Supporting 2-wire HART and 4-wire universal inputs, the FLXA402 accommodates all major glass electrode manufacturers ensuring compatibility with existing Saudi plant sensor inventory. Its dual-channel capability enables simultaneous pH and ORP measurement for chlorination optimization in SWCC and NWC desalination and water treatment facilities. Advanced electrode diagnostics continuously monitor glass electrode impedance and response time, alerting Saudi maintenance teams before measurement drift impacts process quality. The FLXA402's hygienic design meets Saudi food and beverage SASO requirements alongside petrochemical process applications.

Key Features & Benefits
- Dual-channel simultaneous pH and ORP measurement optimizes chlorination dosing and dechlorination control in SWCC seawater desalination plant post-treatment systems.
- Electrode diagnostic function monitors glass membrane impedance, reference junction potential, and asymmetry potential, providing early warning before calibration drift in Saudi water plants.
- Universal 4-wire input compatibility accepts electrodes from all major manufacturers, protecting Saudi plant sensor purchasing flexibility and reducing sole-source dependency.
- HART 7 communication enables remote pH calibration from NWC control rooms, eliminating field access requirements in chlorine-hazardous water treatment environments.
- IP66 weatherproof housing withstands outdoor installation at Saudi coastal desalination plants and outdoor wastewater treatment facilities exposed to Gulf humidity and sandstorms.
Industrial Applications in Saudi Arabia
- Post-treatment pH control in SWCC Shoaiba and Jubail reverse osmosis permeate remineralization for potable water pH correction to NWC distribution standards.
- Chlorination control in NWC water treatment plants for disinfection optimization balancing bacteriological safety with trihalomethane formation minimization.
- Effluent pH monitoring at SABIC and SADARA industrial wastewater treatment plants for compliance with Saudi NCEC discharge permit requirements.
- Cooling tower water pH and ORP monitoring in SEC power stations and Aramco facilities for corrosion and biological growth control.
- Process pH monitoring in SABIC chlor-alkali production for caustic and chlorine quality control within Saudi SASO product specifications.
