LCD liquid crystal display, Chinese menu, easy operation;

Coulometric titration is used, no standard titration solution is needed, and iron sulfate does not need to be calibrated;

Three levels of electrolysis current are available: 10mA, 20mA, 40mA;

COD measurement value can be displayed directly without user calculation;

Allows to store COD calibration values of 10 different standard sample volumes of manganese method and chromium method, which is convenient for users to call;

With data management function, support data review, deletion and printing, the maximum storage capacity is 200 COD measurement values for manganese method and chromium method;

With a standard USB communication interface, it can be connected to a PC.

COD-572 chemical oxygen demand meter adopts coulometric titration method for measurement. It can not only measure CODCr, but also CODMn (also called permanganate index). Based on the coulometric titration method, the operation is simple and fast, and the amount of reagents is small. It is suitable for the determination of CODCr in surface water samples with low COD content, and the determination of CODMn in samples such as tap water.
