Overview

This instrument adopts high-temperature COD reflux digestion method to ensure water sample reaction *. During the digestion process, air cooling reflux mode is used instead of water cooling reflux mode to save water resources. Adding an air cooling system during cooling greatly saves detection time. According to the national standard method (HJ_828-2017), an intelligent mode is added in addition to the manual operation mode to complete the digestion and cooling process with one click operation. Equipped with a dedicated condenser bracket for safer operation.
