Welcome to inquire by phone.

It is an indicator of the amount of reducing substances in water. The reducing substances in water include various organic compounds, sulfides, ferrous salts, etc. But the main thing is organic matter. Therefore, chemical oxygen demand (COD) is often used as an indicator to measure the content of organic matter in water. The higher the chemical oxygen demand, the more severe the pollution of organic matter in the water body. The determination of chemical oxygen demand (COD) varies depending on the reducing substances in the water sample and the measurement method used. The Jieyang COD analyzer also has different measurement values.

Functional features:

1. Time saving: The entire measurement process, including steps such as water sample digestion and colorimetric determination, requires less than 30 minutes. Which COD analyzer is stronger; The instrument comes with 20 standard curves that can be self adjusted and saved. 2. It has minimal secondary pollution to the environment: the reagent volume is one tenth of that of the reflux method, and the amount of waste liquid generated is extremely small; The instrument can automatically calculate and store 10 regression fitting curves. 3. Safe and reliable: the digestion device has anti spray protection, which can effectively prevent water sample overflow caused by insufficient acid concentration; Print current data and all stored historical data

COD analyzer features:

The instrument has low requirements for the location and can adapt well to the following situations:

A single instrument can adapt to water quality monitoring at multiple sampling points. The instrument can be brought to the site for direct measurement, and the COD analyzer can be quoted. Samples from various locations can also be collected in the laboratory for centralized measurement.

B can quickly indicate the reaction status of intermediate processes in the process

Different levels of response will have corresponding characteristic absorption coefficients, and we can use the latter to quickly estimate the former. Of course, you must know the type of measurement object in advance before you can match it.

C can simultaneously deduct the influence of turbidity, and the sample does not need to be processed.
