Bod Cod Online Analyzer by BOQU

Product Overview

Note: the supplied product text actually describes BOQU’s online heavy?metal analyzers (models referenced include TCuG?3050 for total copper and TNiG?3051 for total nickel) using colorimetric spectrophotometry—not a BOD/COD instrument. Below is a concise 5?point summary based on the provided introduction.

Product Features

1) Product overview

Product Value

- BOQU online total heavy?metal analyzer (examples: TCuG?3050 for copper, TNiG?3051 for nickel) is an automatic, bench/tower?style instrument for continuous online monitoring of total heavy?metal concentrations in water.

Product Advantages

- Designed to meet national environmental protection standards, built with quality materials for long service life and stable operation.

Application Scenarios

- User interface via touch screen with automatic recovery/discharge after alarms or power cycles.

2) Product features

- Analytical method: reagent digestion/oxidation (ammonium persulfate) and colorimetric detection (dimethylglyoxime for nickel) with spectrophotometry.

- Measurement ranges: examples given 0.00–2.00 mg/L and 0.10–10.00 mg/L (model-dependent).

- Performance: accuracy ≤±10% (≥0.2 mg/L) or ±0.02 mg/L (

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

- Outputs and interfaces: 4–20 mA (two channels), RS232/RS485 communication. Data saved on alarms and power loss.

3) Product value

- Enables continuous, unattended online monitoring of total heavy metals, supporting regulatory compliance and faster response to pollution events.

- Reduces manual sampling and lab turnaround time, lowering operational costs and improving process control.

- Robust automation and data logging increase measurement consistency and reliability for environmental and industrial water quality management.

4) Product advantages

- Engineered with progressive technology and quality components for durability and cost?effectiveness.

- High configurability (timing, ranges, calibration) to match diverse water matrices and monitoring needs.

- Automatic reagent purge and auto?resume after faults improve uptime and reduce maintenance intervention.

- Multiple communication outputs and touch?screen control simplify integration with plant/monitoring systems.

- Backed by BOQU’s integrated manufacturing, sales and service capabilities and experienced technical team.

5) Application scenarios

- Continuous monitoring of surface water and ambient environmental sites for heavy?metal pollution control.

- Industrial process water and wastewater monitoring in plating, metal processing, mining, chemical and related industries.

- Effluent compliance monitoring at wastewater treatment plants and industrial discharge points.

- Environmental protection projects and on?site regulatory monitoring programs requiring real?time total heavy?metal data.
