IP68 inline COD monitoring sensor for surface water

COD is the abbreviation of Chemical Oxygen Demand. It mainly refers to the consumption of oxidants required for the oxidation reaction of reducing substances in water when they encounter strong oxidants. Its unit is usually oxygen content (mg/L) express. Since most wastewater lakes or rivers contain a large amount of reducing substances such as nitrite and sulfide that are not conducive to the water environment, the COD value is a comprehensive analysis index for determining the content of reducing substances contained in water quality. Therefore, one of the important indicators for measuring the content of organic matter in water is to measure the COD value in water quality, which is one of the important indicators for continuous monitoring of water environment. Because of its online monitoring function, it is widely used in the online continuous monitoring of wastewater lakes, rivers or industrial wastewater. The advantage of this COD351 online COD Sensor is fast response, it can complete the absorption of ultraviolet light within a few seconds, and can quickly process the data of the processor, even if there is a flushing process of the sample pool, it can be guaranteed to be completed within 1 minute For the one-time measurement process of wastewater, its efficiency is unmatched by other COD measurement methods; The COD sensor is easy to use, and the dual-wavelength ultraviolet absorption method COD online monitoring technology can compensate for the interference of the water sample to be tested during the measurement process. The interference effect is deducted in the result calculation, so it is generally not necessary to pretreat the water sample to be tested.
