Tips: How does this sensor compare to traditional membrane-based dissolved oxygen sensors?

Unlike traditional sensors, this fluorescence-based sensor does not require electrolyte solutions or frequent membrane replacement, significantly reducing maintenance efforts and costs. It also has a longer lifespan and is unaffected by water flow or fouling, making it more reliable in long-term monitoring applications. The fluorescence method also provides faster response times and higher accuracy, especially in low-oxygen environments.
