Electrochemical Dissolved Oxygen Sensor Galvanic vs Polarographic Technology for Aquaculture

ByRichard Lv

Introduction: The Critical Role of Dissolved Oxygen in Aquaculture In modern aquaculture, dissolved oxygen (DO) concentration is the single most critical water quality parameter. Whether you operate a high-density recirculating aquaculture system (RAS) for shrimp, an extensive pond for tilapia, or a flow-through salmon farm, maintaining optimal DO levels (typically 5–8 mg/L for most species)…
