COD-572 Chemical Oxygen Demand AnalyzerDetailed product description：

Characteristics of COD-572 Chemical Oxygen Demand Analyzer:

Adopting microcontroller technology and equipped with power-off protection function. Chinese menu display, simple and clear operation.
COD measurement values can be directly displayed without the need for user calculation.
The analysis is simple, fast, and has high accuracy.
No standard titration solution is required, and iron sulfate does not need to be calibrated.
Connected to the TP-16 serial printer, it can print measurement and calibration results (printer purchased by the user).
It can store COD calibration values for 10 different sample volumes of manganese method and chromium method, making it easy for users to call.
It can also store 50 COD measurement values for both manganese and chromium methods.
It has functions such as storage, deletion, retrieval, and printing.
