Product Overview
Note: the provided product description describes the BOQU CODG-3000 Online Chemical Oxygen Demand (COD) Analyzer (potassium dichromate method), not a chlorophyll analyzer. Below is a concise 5‑point summary based on the given details.
Product Features
1) Product overview
Product Value
- Online chemical oxygen demand (COD) analyzer (model CODG-3000) from BOQU.
Product Advantages
- Uses the potassium dichromate digestion/colorimetric method with silver sulfate catalyst and concentrated sulfuric acid; sample heated to ~175 °C in a digestion tank.
Application Scenarios
- Industrial/continuous online instrument with touch-screen display, data logging and standard communication outputs (4–20 mA, RS232, RS485).
2) Product features
- Measuring ranges configurable (examples: 5–1,500 mg/L; 100–5,000 mg/L; 500–15,000 mg/L).
- Accuracy and repeatability: ≤±10% for ≥100 mg/L; tighter absolute error specs for
- Adjustable digestion/measurement timing: digestion 10–120 minutes (minimum measurement period ~35 minutes); sampling interval 55–9,999 min; calibration period adjustable 1–99 days.
- Automatic functions: residual reagent discharge and automatic resume after reset/power cycle; data saved on alarms and power loss.
- Maintenance: typically monthly, ~30 minutes per session.
- Environmental/power specs: recommended +5–28 °C, humidity ≤90% (no dew); AC 220 V supply; compact cabinet dimensions.
3) Product value
- Provides automated, continuous, and repeatable COD monitoring for process control and regulatory compliance.
- Flexible range and timing settings let users adapt the analyzer to different wastewater strengths and process needs.
- Remote outputs and data retention enable integration into control systems and support timely decision-making and reporting.
- Reduces manual testing workload and improves safety by containing digestion and reagent handling inside the instrument.
4) Product advantages
- Established manufacturer (BOQU) with years of water‑quality instrumentation experience and international sales support.
- Comprehensive quality control and up‑to‑date technology compatibility claimed in production.
- Built‑in measures for main interferences: chloride interference can be treated by adding mercury sulfate to form a complex.
- User‑friendly operation: touch screen, automatic reagent purge on restart, adjustable maintenance/calibration schedules.
- Multiple standard outputs for easy integration into plant monitoring systems.
5) Application scenarios
- Continuous monitoring of industrial wastewater (chemical, textile, food, pharmaceutical, petrochemical).
- Municipal sewage treatment plants for influent/effluent COD tracking and process control.
- Effluent compliance monitoring for regulatory reporting.
- Environmental monitoring at discharge points and receiving waters (where online COD trends are needed).
- On‑line process control in manufacturing lines where organic load control is required.
