Product Description
RS485 Online Digital COD Analyzer with UV Method
Advanced digital universal COD analyzer designed for precise measurement of chemical oxygen demand in water using UV254 absorption method with IP66 protection rating.
Product Overview
The DUC2-COD-H is a specialized single-parameter controller with pre-installed DRFN COD analysis software, compatible with various DRFN COD digital sensors. The system employs Spectral Absorption Coefficient (SAC) technology, measuring ultraviolet light absorption at 254nm wavelength to detect organic substances in water.
Key Features & Advantages
- Menu password protection for data confidentiality
- Clock and historical data recording (14,000 data points)
- 3.2-inch LCD display with 128*64 resolution
- Power-off protection with indefinite parameter retention
- No consumables required during measurement process
- Multi-parameter measurement: COD, TOC, turbidity, and temperature
- Dual light sources: 254nm and 365nm UV reference light
- Automatic suspended solids interference elimination and turbidity compensation
Applications
River water, surface water, process water, sewage treatment plants, industrial wastewater, and drinking water monitoring.
