Key Features & Design Advantages
Enhanced Reliability & Efficiency
Engineered for lower failure rates, reduced maintenance requirements, minimal reagent consumption (less than 0.5 yuan per sample), and superior cost-effectiveness.
Advanced Component Design
- Selector Valve Assembly: Flexible reagent timing with minimized dead volume for extended service life
- Micro-Dosing Unit: Precise 0.7 mL per dose measurement with visual photoelectric system
- Sample Introduction Unit: Peristaltic pump with air buffer zone prevents corrosion
- Sealed Digestion Unit: High-temperature, high-pressure operation eliminates volatile gas risks
- Reagent Tubing: Imported modified PTFE transparent tubing with >1.5 mm inner diameter resists clogging
Analytical Principle
The analyzer employs the potassium dichromate digestion method according to National Standard HJ 828-2017. Water samples mixed with potassium dichromate digestion solution, silver sulfate catalyst, and concentrated sulfuric acid undergo high-temperature digestion. The resulting colorimetric change is detected and converted to precise COD values.
Application Scope
Ideal for wastewater with COD values from 10 to 5000 mg/L and chloride ion concentrations below 2 g/L (extendable to 20 g/L based on requirements).
Operational Benefits
Features include automatic data retention during power failure, touchscreen interface, automatic reactant discharge, and state recovery after system resets.
