The features of Chemical Oxygen Demand Analyzeras follows:

1.Applicable for the site at high concentration of chloride ion. It achieves removal by adding mercury sulfate, for chloride ion and mercury ion can form the stable mercury chloride.
2.Special design for industrial user, especially suitable for COD measurement of industrial wastewater and high concentration wastewater before treatment
3.Suitable for measuring the wastewater at COD ranging 10-5000mg/L, automatic switchover of span.
4.Organic unification of classic potassium bichromate oxidation and creative measuring technology.
5.Reliable measurement, low failure rate, free of vulnerable parts. 
6.Low operation cost.
7.Alarm for abnormality and free of data loss in case of power failure.
8.In case of abnormality reset and restoration power supply after power failure, the equipment automatically discharges the residual reagent, and automatically resumes work state. 
9.Touch screen display and directive input, and password protection prevents mis-operation.
