Key Features & Design Advantages
Selector Valve Assembly
Flexible reagent sampling timing and diverse channel configurations with minimized dead volume for easy maintenance and extended service life.
Micro-Dosing Unit
Visual photoelectric system ensures precise reagent measurement with 0.7 mL per dose, eliminating errors from pump tube wear.
Sample Introduction Unit
Peristaltic pump with negative pressure suction creates air buffer zone to prevent corrosion and enhance reagent mixing flexibility.
Sealed Digestion Unit
High-temperature, high-pressure operation accelerates reactions while eliminating corrosion risks from volatile gases.
Reagent Tubing System
Imported modified PTFE transparent tubing with inner diameter >1.5 mm minimizes clogging from water sample particulates.
Analytical Principle
The water sample is mixed with potassium permanganate digestion solution and dilute sulfuric acid, then heated for digestion. After permanganate ions oxidize organic matter, the resulting color change is detected and converted into permanganate index values for output.
Additional Capabilities
- Data retention during abnormal alarms and power outages
- Touchscreen display and command input interface
- Automatic discharge of residual reactants and operational resumption after reset or power restoration
