COD Smart Reflux Digester

The COD Smart Reflux Digester adheres to the fundamental principles of the national standard HJ828-2017 “Water Quality - Determination of Chemical Oxygen Demand - Potassium Dichromate Method,” ensuring the digestion operation of reflux heating at a gentle boil for 2 hours. The preparation and addition quantities of reagent solutions align with the national standard method, guaranteeing reliable and accurate analytical results.

The COD Smart Reflux Digester is widely applicable for water sample pretreatment requirements in fields such as environmental monitoring, soil analysis, food safety testing, and disease prevention and control centers.

• Efficient, Accurate, and Rapid Testing: Standardized operating procedures and precisely controlled test conditions enable rapid detection, ensuring consistent and accurate results.

• User-Friendly Operation with High Automation: The instrument design prioritizes user convenience, featuring an automated control system that allows one-touch setting of parameters like efficiency and time. This minimizes human error and simplifies operational steps.

• Superior Safety Performance: Features a glass frit reflux tube instead of a spherical one, and employs air-cooling + water-cooling technology to replace traditional tap water cooling. This approach conserves water, standardizes instrument operation, and incorporates safety features like overheat power-off, enhancing overall usage safety.

• Easy-to-clean panel: The graphene heating plate features a smooth, flat surface that wipes clean effortlessly, minimizing damage from operational mishandling.

• Environmentally friendly with reduced secondary pollution: Compared to traditional methods, the instrument employs microcomputer technology for timed heating control, enabling uniform heating of the entire conical flask reflux assembly. This achieves energy savings, reduces power consumption, and improves efficiency, aligning with sustainable development requirements.

• Visual operation status feedback: The main unit features status indicator lights that visually reflect the instrument's operational state through color changes, providing intuitive and convenient monitoring.
