HK-8010 Online COD Analyzer
Product Introduction
The HK-8010 Online COD Analyzer is a high-precision chemical oxygen demand (COD) monitoring instrument designed for continuous online water quality analysis in industrial processes and wastewater treatment applications.
The analyzer adopts advanced US dynamic standard reagent addition technology, which improves measurement accuracy and repeatability compared with traditional ion measurement methods. By automatically adjusting reagent addition according to the initial sample absorbance, HK-8010 minimizes interference from other ions and provides reliable COD concentration analysis.
With low reagent consumption, simple operation, robust industrial design, and long-term unattended operation capability, the HK-8010 online COD analyzer is an ideal solution for real-time chemical monitoring and process control.

Performance Features
• High-precision dynamic reagent measurement technology
Uses dual absorbance measurement (ABS1 and ABS2) with automatic standard solution addition to achieve accurate COD calculation.
• Excellent anti-interference capability
Reduces the influence of other ions in samples and improves measurement reliability.
• Continuous unattended operation
Designed for long-term industrial operation with low maintenance requirements.
• Low operating cost
Minimal reagent consumption and fewer moving components reduce daily operating expenses.
• Multi-sample and multi-parameter analysis capability
One analyzer can support multiple chemical indicators for production line monitoring.
• Industrial-grade protection design
IP65/IP66 protective enclosure, corrosion resistance, dustproof structure, and outdoor installation capability.
• Separated chemical and electronic compartments
Sample/reagent pathways and electronic components are installed separately, with positive pressure protection for harsh environments.
• Large data storage capacity
Automatically stores up to 100,000 measurement records.
• Flexible communication interfaces
Supports RS232, RS422, RS485, and MODBUS communication protocols.
• Bilingual operation interface
Chinese and English language switching is available.

Working Principle
The HK-8010 online COD analyzer uses a unique dynamic standard reagent addition spectrophotometric method.
The measurement process includes:
1.The analyzer first measures the original sample absorbance value (ABS1).
2.According to the initial absorbance, the system automatically adds a specific volume of standard solution with known concentration.
3.The mixed sample solution is measured again to obtain the second absorbance value (ABS2).
4.The COD concentration is calculated using the difference between ABS1 and ABS2 through the built-in calculation model.
This dynamic calibration method compensates for sample variations, improves measurement precision, and reduces interference from complex water matrices.
