Unique Design: This product features a distinctive design that ensures lower failure rates, reduced maintenance requirements, minimal reagent consumption, and higher cost-effectiveness compared to similar products.

1. Selector Valve Assembly:

   • Enables flexible reagent sampling timing and diverse channel configurations.
   • Minimizes dead volume for easy maintenance and extended service life.

2. Micro-Dosing Unit:

   • Utilizes a visual photoelectric system for precise reagent measurement, eliminating quantitative errors caused by peristaltic pump tube wear.
   • Achieves accurate micro-dosing with 0.7 mL per dose, significantly reducing reagent usage.

3. Sample Introduction Unit:

   • Employs a peristaltic pump with negative pressure suction, creating an air buffer zone between reagents and the pump tube to prevent corrosion.
   • Simplifies and enhances flexibility in reagent mixing.

4. Sealed Digestion Unit:

   • Operates under high-temperature and high-pressure conditions to accelerate reactions.
   • Eliminates corrosion risks from volatile gases in open systems.

5. Reagent Tubing:

   • Uses imported modified PTFE (polytetrafluoroethylene) transparent tubing with an inner diameter >1.5 mm to minimize clogging by particulate matter in water samples.
