National Standard COD Digestion Equipment

The national standard COD digestion equipment adheres to the fundamental principles of the national standard HJ828-2017 “Water Quality - Determination of Chemical Oxygen Demand - Potassium Dichromate Method.” It ensures 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 National Standard COD Digestion Equipment is widely applicable for chemical oxygen demand sample digestion in environmental protection, scientific research, and industries such as papermaking, petrochemicals, metallurgy, and textile dyeing.

• Independent Temperature Control: 10 independent heating channels maintain constant temperatures without interference. Each heating unit allows customizable digestion temperatures based on water sample characteristics, ensuring samples reach the standard-required micro-boiling state.

• One-Touch Start: Intelligent mode simplifies operation—a single button initiates automatic heating, digestion, reflux, and cooling for each unit according to preset programs.

• Rotating Base: The heating plate features 360° left-right rotation, enabling real-time monitoring of digestion progress and quick access for consumable replenishment or sample retrieval.

• Adjustable Parameters: Heating temperature reaches up to 400°C, with digesting and cooling times freely set between 1-1439 minutes. This enhances instrument versatility and scalability to meet diverse experimental needs.

• Clear Display: Features a built-in 7-inch color LCD touchscreen with a 0-90° adjustable viewing angle, ensuring optimal visibility whether seated or standing. The interface displays real-time unit statuses, digestion timers, and cooling durations.

• Online Upgrades: Supports Wi-Fi connectivity for remote software downloads and automatic updates, enhancing instrument performance, adding new features, or adapting to updated water quality monitoring standards.

• Method Save/Load: Supports saving multiple custom methods. One-click activation enables applications, eliminating repetitive temperature and time adjustments to boost experimental efficiency.

• Copy Function: Once parameters are set for one channel, they can be instantly replicated to the other nine channels, saving time and effort.

• Compliance: Designed and manufactured in accordance with the principles of the environmental standard HJ 828-2017 “Water Quality - Determination of Chemical Oxygen Demand - Potassium Dichromate Method”.
