This study aims to design and implement an Electrical Conductivity (EC) monitoring system in the Balance of Plant (BOP) 2 area, specifically in the demineralized water unit, to facilitate remote monitoring without requiring on-site inspection. The system integrates the EC Analyzer Rosemount 1066, power supply, HMI KTP600, Siemens S7-1200 PLC, and Real-time data visualization using Node-RED with remote access via Portmap.io. The methodology includes literature review, system design, prototype development, and field testing. Test results show that the system operates responsively, with EC reading deviations of approximately ±0.1% and an average delay of 1.93 seconds. The system proves to be accurate, responsive, and suitable for industrial application, with suggestions for future development including SOP creation and system expansion to other plant parameters. This system enables more efficient and safer monitoring by reducing the need for field inspections. Its implementation supports digital transformation in industrial utility management
