Overview

Reflux titration and rapid digestion spectrophotometry are adopted for chemical oxygen demand (COD) detection in laboratory water quality. Among them, reflux titration is complicated, cumbersome, and time-consuming in operation, requiring high skills of operators. No retest is allowed.
EXPEC Technology's SUPEC 5000 Series Fully Automatic COD Water Quality Analyzer is a fully automatic laboratory analysis instrument based on rapid digestion spectrophotometry launched by EXPEC Technology. It complies with Water Quality- Determination of the Chemical Oxygen Demand - Fast Digestion -Spectrophotometric Method (HJ/T399-2007) and integrates reagent preparation, sample addition, digestion, and detection. Embracing significant advantages such as simplicity, high efficiency, cost saving, and suitability for bulk sample detection, it can be used in comprehensive emission, agriculture, forestry, breeding, public health and other fields.
