Digital Water Quality Sensors
COD / BOD / TOC Digital Sensor
Reagent-free online COD, BOD and TOC sensor using UV double-beam absorbance, with RS485 Modbus output for ETP/STP online monitoring.
- Reagent-free UV double-beam measurement
- COD, BOD and TOC from one sensor
- RS485 Modbus RTU output
- Low maintenance for continuous monitoring
COD / BOD / TOC Digital Sensor specifications
| Output | RS485 (Modbus RTU), digital |
|---|---|
| Use | Online monitoring systems, PLC/SCADA, data loggers |
| Detailed specifications | Available on request |
This digital sensor estimates COD, BOD and TOC by measuring UV absorbance of organic matter with a double-beam optical method. Unlike laboratory tests it needs no reagents and gives a reading every few seconds, which makes it the core sensor in online effluent monitoring systems.
Typical applications
- ETP and STP outlet monitoring for CPCB/SPCB
- Process control of biological treatment
- Surface water quality monitoring
Digital sensors connect directly to the Senvolt online monitoring system or any Modbus master. Send us the application details and we will confirm the right configuration and lead time.
