Product Features
1) Product overview
Product Value
- BOQU CODS-3000 is an online, immersion UV (254 nm) COD meter designed for continuous, reagent-free monitoring of soluble organic matter in water.
Product Advantages
- It measures the 254 nm spectral absorption coefficient (SAC254) and converts that signal into a COD value under applicable conditions.
Application Scenarios
- The system comprises a transmitter (IP65) and an immersion sensor (IP68) with a standard 10 m cable (extendable to 100 m).
2) Product features
- UV 254 nm absorption-based measurement (SAC254) for soluble organics; continuous, real-time monitoring.
- Reagent-free operation—no chemical reagents and no secondary pollution.
- Direct immersion sensor for in-situ measurement (no sampling or pre-treatment).
- Automatic cleaning function and low maintenance design.
- Digital output (RS485 Modbus RTU), two 4–20 mA outputs, and three relay outputs for alarms/control.
- Fast response and reported accuracy of ±5%; temperature range -15 to 60 °C.
3) Product value
- Enables continuous, timely data for process control and rapid decision-making in wastewater treatment and industrial processes.
- Reduces operating costs and safety risks by eliminating reagents and frequent manual sampling.
- Improves compliance and environmental management by providing reliable influent/effluent monitoring and early warning of organic load changes.
- Minimizes downtime and maintenance effort through automatic cleaning and robust sensor design.
4) Product advantages
- Robust, field-ready construction (sensor IP68, transmitter IP65) suitable for harsh environments.
- Flexible communications (Modbus RTU over RS485, analog outputs, relay outputs) for easy integration with PLCs and SCADA.
- Wide measuring ranges available (0–200 mg/L and 0–1000 mg/L with 2 mm optical path) to suit different applications.
- Long cable capability (standard 10 m, extendable to 100 m) for versatile installation.
- Backed by BOQU’s manufacturing scale and global sales/support network.
5) Application scenarios
- Continuous monitoring of organic matter load in municipal and industrial wastewater treatment plants (influent and effluent).
- Surface water quality surveillance and river monitoring for dissolved organics.
- Monitoring industrial discharge streams (food processing, chemical, pulp & paper, etc.).
- Aquaculture and fishery discharge water monitoring.
- Any process or environmental installation requiring real-time, reagent-free tracking of soluble organic content where a UV254-to-COD correlation is appropriate.
