Description

Product Description

An important indicator of water pollution is chemical oxygen demand, also known as chemical oxygen demand (chem-icaloxygendemand), referred to as COD. It directly reflects drinking water safety and environmental pollution issues. In order to effectively realize real-time online monitoring of COD changes in water quality, and reasonably make up for the shortcomings of chemical and electrochemical detection methods, delfino has developed a new online water quality (COD) monitor based on the principle of ultraviolet (UV) absorption. The ultraviolet absorption Water Quality Monitor mainly uses spectral analysis technology, without any chemical pretreatment, no secondary pollution, and can truly realize online and real-time monitoring. Can comprehensively improve the technical level of water quality monitoring. The multi-wavelength ultraviolet COD Sensor automatic online monitor uses the optical absorption principle of substance molecules to monitor the COD concentration of water samples in real time and online. The instrument is placed outside the water body, and the continuous and stable collection of water samples is completed through the automatic sampling unit; the long-life pulse xenon lamp is used as the light source; the characteristic absorbance of organic matter in the ultraviolet spectrum is used to detect the accurate real-time concentration of COD in the water body; the wavelength of 546nm is used as the Reference beam to eliminate the influence of water sample turbidity and chromaticity; The COD sensor has install automatic cleaning device to ensure accurate measurement。

Features Of Chemical Oxygen Demand Sensor

●?Can measure parameters such as COD, TOC, turbidity and temperature；

●?The COD sensor uses UV254 nano-ultraviolet absorption measurement method,require no consumable；

● Eliminate the interference of suspend solids

● Drop-in installation, no need to digest the tested sample, real-time response, no need to wait；
●?RS485 interface, standard Modbus, support access to standard industrial control system and COD Controller.
