Applications
Aquaculture & Fish Farming: Monitor DO levels to ensure optimal fish health, prevent stress and mortality, and maximize growth rates in ponds, tanks, and recirculating aquaculture systems (RAS).
Wastewater Treatment: Track DO in aeration tanks, activated sludge processes, and effluent streams for process control, regulatory compliance, and treatment optimization.
Environmental Monitoring: Assess water quality in rivers, lakes, streams, and wetlands for ecological studies, pollution monitoring, and habitat assessment.
Food & Beverage Production: Control dissolved oxygen in brewing, winemaking, beverage bottling, and food processing to prevent oxidation and extend shelf life.
Hydroponics & Aquaponics: Optimize root zone oxygen for maximum plant growth, nutrient uptake, and system health.
