Instrument function
1. Chinese menu, LCD display, simple operation
2. using potassium dichromate colorimetric method
3. read the COD results, without other methods such as titration analysis
4. two point calibration (zero oxygen and full scale calibration)
5. support for access, delete and print, can be connected with a TP-16 printer, and can store 200 sets of measurement data
6. digestion device has the advantages of compact structure, sealing digestion method. At the same time 21 sample digestion reaction, reduce energy consumption
7. digestion at room temperature to 165 DEG C set arbitrarily, and over temperature alarm device
8. the digestion time was 0 ~ 120min set, the end of the reaction is automatically closed, convenient operation
