working principle
Working principle of portable COD (Cr) analyzer TP2211
- The portable COD analyzer is a laboratory water quality analyzer that uses the principle of photoelectric colorimetry for measurement. According to the Lambert-Beer law: when a beam of monochromatic parallel light passes through a colored solution, part of the light energy is absorbed by the solution. If the thickness of the liquid layer remains unchanged, the degree of light energy absorbed is proportional to the concentration of the colored substance in the solution.
- TP2211 portable COD (Cr) meter can quickly measure the COD content in enterprise wastewater.

- Precautions
1. To improve the accuracy of the test, the mutual influence of samples during the test should be reduced, and the digestion tubes and tube covers of blanks, standard samples, and samples should be fixed to reduce the error caused by the operation.
2. According to the concentration value of the sample to be tested, the corresponding standard curve should be selected.
3. When the portable COD analyzer has obvious faults, the user should not open it for maintenance by himself, please contact the manufacturer in time.
