Fink COD detector

COD detectorAlso known as a chemical oxygen demand detector, it is an instrument used to analyze the content of organic pollutants in water samples. It can detect various types of water samples, including drinking water, sewage, river water, lake water, etc.COD detectorUV digestion or chemical oxidation methods are commonly used to determine COD concentration in water bodies. Their detection is fast, accurate, and convenient, making them important tools and equipment for water quality monitoring and environmental monitoring.

1COD detectorProduct Category

1. HandheldCOD detector

handheldCOD detectorIt is an independent and lightweight instrument suitable for field sampling and on-site testing. It uses chemical oxidation method for COD determination, and the instrument can directly read the COD value, which is relatively simple and easy to use, with the advantages of real-time, mobility, and immediacy. handheldCOD detectorMainly used for water quality testing in fields such as water supply, drainage, and aquaculture.

2. DesktopCOD detector

desktopCOD detectorIt includes two types: ultraviolet digestion type and chemical oxidation type, which are commonly used for quantitative analysis of COD concentration in laboratories, factories, water plants, and other fields. Compared to handheld devicesCOD detectorCompared to desktopCOD detectorIt needs to be fixed on the table for testing, with higher accuracy and stability.

3. OnlineCOD detector

onlineCOD detectorIt is a 24-hour real-time monitoring and data collection of water quality information through unmanned operation, widely used in environmental protection fields such as sewage treatment plants, aquaculture, and solid waste treatment. It can timely detect abnormal changes in water quality, improve treatment efficiency, and provide effective means for water environment protection.

IICOD detectorPrinciple of use

1. Chemical oxidation method

Chemical oxidation is a method of indirectly determining COD values by oxidizing organic matter in a sample with a strong oxidant, reducing it to CO2 and H2O. In COD detection, the sample is added to a strong oxidant with a known volume, shaken and heated in a certain proportion. After the reaction is complete, the COD analyzer calculates the COD value by comparing the color difference of the test solution.

2. UV digestion method

The ultraviolet digestion method is a relatively novel COD determination method. This method uses ultraviolet radiation to irradiate the sample, decomposing the organic matter in the sample into volatile substances and converting them into CO2 and H2O. During the detection process, the sample is placed in a UV reactor within a certain temperature range for a period of time, and the COD value is calculated based on the consumption of oxygen content in the reactor.

IIICOD detectorApplication advantages
