Environmental Requirements: Temperature-controlled indoor environment (5-40°C recommended); humidity 45-85%.12. Power Supply: AC220±10% V, 50±1% Hz, 5A.13. Dimensions: H1500 × W500 × D450 (mm).14. Additional Features:Data retention during alarm or power failure;Touchscreen display and command input;Automatic residual reactant discharge and state recovery after power restoration or abnormal reset.>>FeatureUnique 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.Selector Valve Assembly:Enables flexible reagent sampling timing and diverse channel configurations.Minimizes dead volume for easy maintenance and extended service life.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.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.Sealed Digestion Unit:Operates under high-temperature and high-pressure conditions to accelerate reactions.Eliminates corrosion risks from volatile gases in open systems.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.>>Analytical PrincipleThe mixture of the water sample, potassium dichromate digestion solution, silver sulfate solution (added as a catalyst to enhance oxidation of linear aliphatic compounds), and concentrated sulfuric acid undergoes high-temperature digestion. During this process, the dichromate ions oxidize organic matter in the solution, causing a visible color change. The analyzer detects this colorimetric shift and converts it into a corresponding COD (Chemical Oxygen Demand) value for output.
