SC 4500

🧪 What This Data Means — For Quick Client Selection

✔ Dedicated FRC measurement
SC4500 measures free (available) chlorine—essential for disinfection control in drinking water and reuse streams.

✔ Amperometric sensor compatibility
Hach’s membrane/optical chlorine probes deliver reliable readings with fast process response.

✔ Dual outputs + alarms
4–20 mA and configurable relays enable automated control of dosing pumps and compliance alarms.

✔ Robust for plant environments
IP65/NEMA 4X ensures reliable field performance in water/wastewater and industrial utilities.

✔ Graphical LCD helps validation
Trend display helps operators monitor FRC changes over time without additional software.

✔ Integration with SCADA/PLC
Modbus/serial communication streamlines data logging, remote monitoring, and automation.

🧠 Typical Use Cases

• Drinking Water Treatment Plants (WTP) — ensure safe residual chlorine levels to distribution systems

• Secondary Disinfection Control — optimize chlorine dosing, reduce chemical cost

• Recycled/Reuse Water Monitoring — ensure compliance before reuse or discharge

• Cooling Water Lines — prevent biofouling and corrosion

• Process Utility Loops — maintain consistent sanitizer levels
