COD Analyzer Product Overview
The PRE1053-COD High Quality COD Analyzer for Waste Water utilizes the ultraviolet absorption method, integrating extensive application insights and numerous upgrades from its predecessors. This advanced version features a compact design and combines the original split cleaning brush into a single sensor, simplifying installation and enhancing reliability.
The PRE1053-COD analyzer operates without reagents, making it pollutant-free, economically advantageous, and environmentally friendly. It supports long-term online water quality monitoring with automatic compensation for turbidity interference. The built-in automatic cleaning device ensures excellent stability even during extended monitoring periods.
COD Analyzer Test Principle
Many organic compounds dissolved in water absorb ultraviolet light. By measuring the absorption level of 254nm wavelength ultraviolet light by these organic compounds, the PRE1053-COD analyzer determines the total quantity of organic pollutants present in the water. The analyzer uses two light sources: one emitting 254nm ultraviolet light and the other providing turbidity compensation. This dual light source setup automatically mitigates interference from suspended substances in the water, ensuring more stable and dependable measurements.
Key Features of the PRE1053-COD High Quality COD Analyzer for Waste Water
- Digital Sensor with RS-485 Output: Supports Modbus protocol for seamless integration and data communication.
- Reagent-Free Operation: Eliminates the need for reagents, reducing pollution and offering more economical and environmentally friendly operation.
- Multi-Parameter Measurement: Capable of measuring parameters such as COD, TOC, turbidity, and temperature.
- Automatic Turbidity Compensation: Ensures excellent test performance by automatically compensating for turbidity interference.
- Self-Cleaning Brush: Prevents organisms from attaching to the sensor, significantly extending the maintenance period.
