Online Cod Analyzer Wastewater Online COD BOD Analyzer Wholesale - BOQU
Product Overview
- CODG-3000 Online COD Analyzer from BOQU is an industrial online analyzer for continuous measurement of chemical oxygen demand (COD) in wastewater.
- It uses the standard potassium dichromate digestion/colorimetric method (digestion at 175 °C) and displays COD directly by colorimetric conversion.
- Designed for indoor installation with touchscreen operation and data logging; available for wholesale supply.
Product Features
- Measurement principle: potassium dichromate oxidation with silver sulfate catalyst; chloride interference removed with mercury sulfate.
- Measuring ranges configurable (examples: 5–1,500 mg/L; 100–5,000 mg/L; 500–15,000 mg/L).
- Accuracy/precision: ≤±10% when ≥100 mg/L; ≤±8 mg/L (or ≤±6 mg/L repeatability) when
- Adjustable digestion time (10–120 min; typical minimum measurement period 35 min), sampling interval (55–9,999 min), and calibration period (1–99 days).
- Outputs: 4–20 mA (two channels), RS232 and RS485; touchscreen display; saves data on alarms and power loss; automatic residual reagent discharge on reset.
Product Value
- Provides continuous, reliable COD monitoring for process control, compliance reporting and early detection of effluent issues.
- Reduces manual sampling and lab testing costs and turnaround time.
- Enables automated data output and integration with control systems for operational decision-making.
- Monthly maintenance requirement and automated recovery features minimize downtime.
Product Advantages
- Uses a standardized, widely accepted COD method ensuring comparability with laboratory results.
- Wide dynamic measuring range and adjustable parameters to suit different wastewater strengths and applications.
- Robust interference handling (mercury sulfate for chloride) and solid repeatability and accuracy specifications.
- Multiple communication outputs and touchscreen operation for easy integration and user-friendly operation.
- Manufactured under industry standards with international certifications and backed by BOQU’s service/support.
Application Scenarios
- Municipal wastewater treatment plants for influent/effluent monitoring and process control.
- Industrial effluent monitoring in sectors such as chemical, pharmaceutical, textile, food & beverage, and paper mills.
- Real-time compliance monitoring at discharge points and environmental monitoring stations.
- On-line process monitoring in industrial production lines and research facilities that require continuous COD data.
