BOQU Chlorophyll Online Analyzer Chlorophyll Online Analyzer Quality Assurance

Product Overview

Note: the detailed specification you provided describes the CODG-3000 Chemical Oxygen Demand (COD) online analyzer (potassium dichromate method), not a chlorophyll analyzer. I have summarized the information you gave, but please confirm whether you want this COD analyzer summarized or you can provide the actual chlorophyll analyzer specs for an accurate summary.

Product Features

1) Product overview

Product Value

- BOQU online analyzer designed under compatible-design principles with internal quality control and R&D support.

Product Advantages

- The supplied specification describes the CODG-3000 Online Chemical Oxygen Demand (COD) Analyzer using the potassium dichromate colorimetric digestion method.

Application Scenarios

- Built for continuous online monitoring, touch-screen control and automated workflows for routine industrial or environmental water-quality measurement.

- Marketed as delivering economic benefits and reliable quality assurance for water monitoring needs.

2) Product features

- Measurement principle: potassium dichromate digestion/colorimetric method (chromium VI → chromium III color change).

- Measuring ranges offered: multiple ranges (examples given: 5–1,500 mg/L; 100–5,000 mg/L; 500–15,000 mg/L COD).

- Accuracy and repeatability: ≤±10% for ≥100 mg/L; absolute errors and repeatability specifications for

- Adjustable measurement/digestion time (minimum measurement period ~35 min; digestion time adjustable 10–120 min).

- Sampling modes: programmable sampling interval and integrated time measurement; calibration interval adjustable (1–99 days).

- Outputs: 4–20 mA (2 channels), RS232, RS485; touch-screen display and command input.

- Other: automatic discharge of residual reactants after reset/power cycle, data saved during alarms or power-off, recommended indoor ambient temperature +5–28 °C.

3) Product value

- Enables continuous, automated, and reliable monitoring of COD for process control and regulatory compliance.

- Reduces manual sampling and lab-testing costs by providing online real-time or frequent results.

- Improves operational decision-making (process optimization, early detection of pollution events).

- Supports traceable data logging and alarm records for quality assurance and reporting.

- Minimizes downtime through automated purge and straightforward monthly maintenance.

4) Product advantages

- Established chemical method (potassium dichromate) providing broad dynamic range and robust signal generation.

- Flexible configuration: multiple concentration ranges and adjustable digestion/measurement timing to suit varied water matrices.

- Good accuracy and repeatability specifications for both high and low concentration ranges.

- Automated sample handling features (residual reactant discharge, programmable calibration/maintenance) lower operator workload.

- Standard industrial communications (4–20 mA, RS232/RS485) for easy integration with SCADA/DCS and data systems.

- Backed by BOQU’s technical team, R&D and QC processes for product support and reliability.

5) Application scenarios

- Municipal and industrial wastewater treatment plants for continuous effluent monitoring and process control.

- Industrial effluent monitoring in sectors producing organic loads (chemical, textile, food & beverage, paper).

- Environmental monitoring where COD is tracked in receiving waters or discharge compliance is required.

- On-site water quality assurance in large facilities and centralized monitoring stations.

- Laboratory support for routine online screening to reduce sample throughput for confirmatory lab tests.
