The KNF-103B dissolved oxygen sensor uses self-developed fluorescent materials to measure the concentration of dissolved oxygen in water non destructively. It has the advantages of no pollution, long service life, good stability, and low maintenance difficulty. The unique optical detection method of the measuring probe can effectively eliminate the interference of chemical substances such as pH fluctuations, ammonia nitrogen, or heavy metals in water, thereby providing more stable and accurate measurement results over a longer period of time. This product is suitable for measuring and controlling dissolved oxygen concentration in water industries such as aquaculture (such as South American white shrimp, eel, osmanthus fish, etc.) and environmentally friendly water treatment.

Built in temperature sensor, automatic temperature compensation, RS485 output, can be networked without the need for a controller!
