Note: the detailed text you provided describes BOQU’s TCdG-3059 Online Total Cadmium Analyzer. Below is a concise five?point summary based on that description.

Product Features

1) Product overview

Product Value

- The TCdG-3059 is an online automatic total cadmium analyzer by BOQU. It uses the TPPS4 spectrophotometric method to quantify cadmium: cadmium in a sample forms a colored complex in alkaline conditions, and the analyzer measures the color change and converts it to a cadmium concentration. The instrument is designed for continuous, unattended online monitoring in accordance with national environmental protection standards.

3) Product value

- Provides continuous online cadmium monitoring to support regulatory compliance and rapid response to pollution events.

- Automates sample digestion and colorimetric measurement, reducing lab workload, manual sampling and turnaround time.

- Delivers reliable, time?series data and alarmed measurements that help operators detect trends, prevent breaches, and optimize treatment processes.

- Data retention on alarm/power loss preserves records for audits and troubleshooting.

4) Product advantages

- Designed and manufactured with an orderly production process for stable, repeatable performance.

- Adjustable digestion, sampling and calibration parameters allow tailoring to different water matrices and monitoring needs.

- Relatively high sensitivity and specified accuracy across low and mid concentration ranges.

- Built?in automatic discharge of residual reactants and automatic resume after reset/power?up improve safety and uptime.

- Multiple communication outputs and touchscreen interface simplify integration into SCADA/DCS and ease of operation.

- Low routine maintenance frequency (monthly short service) reduces operating costs.

5) Application scenarios

- Continuous online monitoring of cadmium in surface waters (rivers, lakes) for environmental surveillance.

- Process and effluent monitoring in industrial plants (metal finishing, plating, battery manufacturing, electroplating, chemical factories).

- Industrial wastewater treatment plant influent/effluent control and compliance monitoring.

- Regulatory monitoring stations and environmental laboratories needing automated field or indoor online analyzers.

- Any facility requiring remote data output to control systems for alarms, trend analysis and process control.
