KZCOD-210 Self-Cleaning Digital COD Sensor
1. Core Advantages:
• Digital Output
It is a digital type sensor with direct RS‑485 signal output.
It fully matches and supports MODBUS/RTU communication protocol.
• Dual‑Optical Anti‑Interference
It applies dual optical path measuring method with 254 nm and 550 nm reference light.
This design offsets interference brought by water turbidity and color tone.
• Long‑Life Light Source
Equipped with imported UV254 LED cold light source.
It features long service life and very low data drift.
Built-in optical filter guarantees stable performance and less external interference.
• Multi‑Parameter Measurement
It can monitor COD, TOC, turbidity and temperature at the same time.
No chemical reagents needed, and no sample digestion process required.
• Self‑Cleaning & Corrosion‑Resistant
Comes with integrated self-cleaning function.
The probe surface goes through anti-corrosion treatment.
It responds fast during operation and consumes no chemicals at all.
