High End Cod Analyser at Sale

Product Overview

The BODG-3063 Online BOD Analyzer by BOQU is an industrial-grade online biochemical oxygen demand monitor for continuous measurement of organic pollution in water. It uses a potassium dichromate oxidation (colorimetric) digestion method (heated to ~165 °C) to convert color change into a BOD value. The unit is touch-screen controlled, saves data during alarms or power loss, and automatically discharges residual reactants after reset/power-up.

Product Features

- Measurement range: 10–1500 mg/L BOD (customizable beyond range).

- Accuracy and precision: ≤±10% (≥50 mg/L) or ≤±5 mg/L (

- Flexible timing: minimum measurement period ~50 min; digestion time adjustable 5–120 min; sampling interval 55–9999 min; calibration interval adjustable 1–99 days.

- Outputs and connectivity: 4–20 mA (two channels), RS232, RS485.

- Practical design: indoor ambient operation recommended (+5–28 °C, humidity ≤90% no dew), monthly maintenance (~30 min), AC220V power, and compact footprint (1450 × 510 × 450 mm).

Product Value

The analyzer delivers reliable, near-real-time BOD monitoring to support compliance, process control and environmental protection. It reduces reliance on time-consuming lab assays, enables faster reaction to pollution events through alarms and data logging, and supports certification/QS/HACCP requirements for food and drinking water producers. The broad measurement range and adjustable settings make it suitable for diverse effluents and process streams.

Product Advantages

- Wide dynamic range and good accuracy for both low and high BOD concentrations.

- Adjustable digestion and sampling schedules for tailored monitoring strategies.

- Automatic residual-reactant discharge and data retention enhance reliability and reduce downtime after alarms or power interruptions.

- Multiple industrial outputs for easy integration with control systems and SCADA.

- Backed by BOQU’s tested design, established brand presence and customer-focused service, offering proven field performance and adaptable solutions.

Application Scenarios

- Industrial wastewater monitoring (chemical, pharmaceutical, food & beverage, pulp/paper).

- Power plants and agricultural runoff monitoring.

- Drinking water factories and food plants for QS/HACCP compliance and quality control.

- Municipal sewage and wastewater treatment plant process control and performance verification.

- Environmental research and on-site effluent compliance monitoring requiring continuous BOD data.
