Test package

Do you often encounter the following problems during water quality testing? Outdoor testing is difficult, with high testing costs, poor experimental conditions, and long testing cycles. Now we haveTest packageEverything is nothing.

COD chemical oxygen demand is a chemical method for measuring the amount of reducible substances that need to be oxidized in water samples. It is the oxygen equivalent of substances (usually organic matter) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent, and sewage. In the study of river pollution and industrial wastewater properties, as well as the operation and management of sewage treatment plants, it is an important and rapidly determinable organic pollution parameter, usually represented by the symbol COD.

Fink COD FastTest packageApplied to the Yangtze River Basin pollution investigation project led by the Ministry of Ecology, 62 cities participated in the investigation, with a high application rate of 82%, and received high recognition from environmental protection departments in various cities. More than 6000 service enterprises. We have a professional R&D team and over 1100 CMA certified third-party testing laboratories. For complex water samples, our company can provide free testing, diagnosis, and analysis to customize your exclusive solution.

1. Simple: The operation method is simple and can be carried out without the need for specialized technical personnel;

2. Convenient: easy to carry, disposable, suitable for rapid on-site testing;

3. Fast: The detection speed is fast, and it only takes a few minutes to complete the determination of a sample.

The oxidant used in the COD (Chemical Oxygen Demand) measurement method in the COD rapid detection package will cause changes in reaction rate with different reaction times and temperatures. Users should pay attention to the color development time and water sample temperature during use. Color development takes 5 minutes at around 10 ℃, 4 minutes at around 20 ℃, and 3 minutes at around 30 ℃. Due to the fact that COD is a comprehensive indicator, and the oxidant used in this product does not work on all substances, the detection results of this product are usually lower than those obtained after digestion.
