YSI’s analog chlorine sensors are engineered for precise, continuous measurement of free chlorine in clean water applications. Designed for long-term reliability, these amperometric chlorine sensors provide highly accurate data essential for maintaining safe and compliant water quality in municipal drinking water, distribution networks, and industrial process water.
These chlorine sensors integrate seamlessly into the YSI Water Monitoring Panel Solution, delivering reliable, real-time multi-parameter data for professionals seeking efficient water process monitoring and control.
pH-Compensated: Each sensor includes built-in pH compensation, reducing the impact of pH fluctuations on chlorine readings. This leads to more stable and reliable measurements over extended operational periods, even in varying water chemistries.
Flexible Measurement Ranges: available in two measurement ranges:
0–2 mg/L for low-level free or total chlorine monitoring
0–20 mg/L for broader process control needs (free chlorine only)
Advanced Features with IQ SensorNet: When connected to IQ SensorNet controllers, these sensors are automatically recognized and supported by advanced features such as:
- Digital signal conversion
- Multi-parameter system compatibility
- Remote diagnostics and data logging
- Modbus RTU, Profibus, and Ethernet/IP communication protocols
- Custom alarm relays and control logic for real-time process automation
Low Maintenance, Long-Term Performance: Built with durable materials and stable electrolyte systems, the sensors require minimal maintenance, offering lower total cost of ownership and improved operational efficiency when compared to other measurement methods
Common Applications:
- Municipal drinking water treatment plants
- Distribution systems and booster stations
- Industrial water disinfection systems
- Food & beverage process water monitoring
- Secondary disinfection and residual control
