Product Description
UV Absorption COD Sensor with RS485 Digital Communication
Measurement Principle
This advanced UV absorption sensor utilizes 254 nm wavelength to measure dissolved organic compounds in water. The absorbance data correlates with TOC, COD, and BOD concentrations, providing high-performance online monitoring without requiring consumables.
A reference measurement at 530 nm compensates for particle interference and establishes turbidity parameters. The integration of state-of-the-art UV LED technology with rigorous ignition management ensures optimal signal variance and measurement accuracy.
Applications
- Urban wastewater treatment: monitoring organic load variations throughout input, treatment, and output processes
- Industrial effluent treatment systems
- Surface water quality monitoring
- Fish farming and aquaculture (freshwater)
- Drinking water: monitoring organic matter in raw water, oxidation processes, coagulation, and activated carbon filtration
Key Advantages
- Multi-parameter measurement: SAC254, CODeq, TOCeq, BODeq & Turbidity eq
- UV 254 spectral absorption technology without reagents or consumables
- Automatic turbidity compensation for accurate readings
- Interference-proof design with built-in pre-amplification and digital signal processing
- Compatible with recorders, transmitters, remote management systems, and PLCs via Modbus RS-485
- Comprehensive data management: calibration, history, user, and measurement data processed directly in the probe
