AquaSense-COD
Reagent-free UV-absorption COD sensor that also reports TOC, BOD, turbidity, and temperature, with automatic turbidity compensation and a self-cleaning brush.
AquaSense-COD is a digital RS485 / Modbus RTU sensor that uses UV absorption to deliver continuous COD, TOC, BOD, turbidity, and temperature readings without reagents or consumables. Automatic turbidity compensation, a self-cleaning brush, and immunity to chloride interference give it a reliable, fast-response duty cycle in wastewater and surface-water monitoring.
Reagent-Free UV
UV-absorption measurement without reagents or consumable kits.
Multi-Parameter Output
Simultaneous COD, TOC, BOD, turbidity, and temperature values.
Self-Cleaning Brush
Built-in wiper prevents biofouling for long maintenance intervals.
Chloride-Tolerant
UV optics deliver stable readings without chloride interference.
No Reagents
Reagent-free optical measurement keeps the deployment clean and low-maintenance.
Auto-Cleaning Option
Optional self-cleaning wiper resists biofouling for long-duration service.
Digital Output
RS485 with Modbus RTU protocol for easy logger and PLC integration.
Temperature Compensation
Built-in temperature sensor with automatic compensation.
Continuous Monitoring
Designed for unattended in-line and in-situ deployments.
Stable & Drift-Resistant
Tight optical path and software algorithms minimise long-term drift.
Overview
AquaSense-COD is a UV-absorption sensor that reports chemical oxygen demand alongside total organic carbon, biochemical oxygen demand, turbidity, and water temperature on a single RS485 / Modbus RTU interface. The reagent-free optical method eliminates consumables and waste — a real advantage for unattended deployments and long-term programs.
Automatic turbidity compensation, a self-cleaning brush, and chloride-immune optics produce stable readings even in challenging effluent and surface-water samples, with response times of a few tens of seconds. The sensor is well-suited to municipal and industrial wastewater discharge monitoring, environmental compliance, and process-water surveillance.
