Product Description
Product Overview
The RS485 Digital COD Analyzer with UV254nm Sensor is a professional water quality monitoring system designed for precise measurement of Chemical Oxygen Demand (COD) in various water applications. This integrated solution combines a robust controller with an advanced UV absorption sensor for reliable, continuous monitoring.
Measurement Principle
The COD analyzer utilizes Spectral Absorption Coefficient (SAC) technology, measuring the absorption degree of ultraviolet light at 254nm wavelength by organic substances in water. This non-contact method provides accurate detection of organic matter substitution without chemical consumables.
Key Features & Advantages
- Password-protected menu system for data confidentiality
- Comprehensive time and historical data recording (14,000 data points)
- 3.2-inch LCD display with power-off protection for indefinite parameter retention
- Multi-parameter measurement: COD, TOC, turbidity, and temperature
- Automatic suspended solids interference elimination and turbidity compensation
- No consumables required during measurement process
- Dual relay control and analog current output capabilities
Application Areas
- Compliance monitoring and regulatory reporting
- Wastewater treatment process optimization
- Process control algorithm development
- Cross-connected sewer identification
- Pollution source identification and incident severity assessment
- Advanced treatment monitoring and effluent protection
