Overview

Typical applications for drinking water monitoring: water quality control, sewage monitoring and control: inflow monitoring, discharge monitoring, process water control: industrial facility process monitoring, water treatment control, dual wavelength ultraviolet absorption sensor is a COD online monitoring instrument designed specifically for measuring dissolved organic matter in water (drinking water/surface water/sewage)

Product Details

Typical applications
Drinking water monitoring: water quality control Sewage monitoring and control: inflow monitoring Emission Monitoring
Process water control: Industrial facility process monitoring Water treatment control
The dual wavelength ultraviolet absorption sensor is specifically designed for measuring water (drinking water)/surface water/Designed for dissolving organic matter in wastewaterCODOnline monitoring device. It is directly immersed in water and measured at wavelength254nmOrganic matter dissolved in water that absorbs ultraviolet light, i.eSAC254Simultaneously measuring550nmWavelength is used for turbidity compensation, and the content of organic matter is calculated using Lambert Beer's lawCODexpress. hereCODThe unique dual wavelength and dual beam structure of online monitoring sensors can effectively eliminate the interference of factors such as turbidity, power supply fluctuations, and component aging in the sample on the measurement results, thereby improving measurement accuracy. shouldCODOnline monitoring devices have the characteristics of automatic cleaning and no need for chemical reagents, making them the choice for controlling water treatment process parameters under suitable conditions.

Various optical paths to choose from（0.5mm, 1mm, 2mm, 5mm, 20mm，35mm）To meet the measurement needs of various parameters and ranges.

Adopting sapphire light window and attached with special anti hanging material coating, combined with automatic blowing device or cleaning brush, it is basically maintenance free.
