COD Sensor Is Equipped With Automatic Temperature Compensation And Does Not Require Reagents, Thus Avoiding Contamination
1. Product Overview
The KNF-108A COD sensor is a UV absorption COD sensor. Based on numerous application experiences, it has undergone multiple upgrades on the original basis. Not only is it smaller in size, but it also integrates the original split cleaning brush into one, making installation more convenient and offering higher reliability.
KNF-108A requires no reagents, causes no pollution and is more economical and environmentally friendly. Water quality monitoring can be conducted online without interruption. It automatically compensates for turbidity interference and is equipped with an automatic cleaning device, ensuring excellent stability even under long-term monitoring.

2.Test principle
Many organic substances dissolved in water have an absorbing effect on ultraviolet light. Therefore, by measuring the degree to which these organic substances absorb ultraviolet light, the total amount of organic pollutants in water can be assessed. The KNF-108A sensor adopts two light sources, one ultraviolet light and the other 550nm reference light. It can automatically eliminate the interference of suspended substances, thereby achieving more stable and reliable measurement values.
