Product details
Product Introduction/ Product introduction
The water quality COD online sensor KNF-108A is an online sensor used to measure the chemical oxygen demand of various types of water quality to help evaluate water quality. No need for reagents, no pollution, more economical and environmentally friendly. Continuous online water quality monitoring is possible. Automatically compensates for turbidity interference, equipped with an automatic cleaning device, and maintains good stability even after long-term monitoring.The KNF108A COD sensor adopts dual light sources of 254nm and 365nm, which can automatically correct the interference of suspended substances. It also has temperature automatic compensation to achieve more stable and reliable measurement values. No reagents are needed, and it will not cause secondary pollution. The later operation and maintenance are extremely simple with minimal consumables, making it more economical and environmentally friendly. It can continuously monitor water quality online, automatically compensate for turbidity interference, and has an automatic cleaning device. Even long-term monitoring still has good stability.
