Application
①Aquaculture Farming:
Ideal for continuous dissolved oxygen tracking in ponds, tanks, and recirculating aquaculture systems (RAS), where harsh water conditions—such as high organic matter, algae blooms, or chemical treatments—are common. The sensor’s bacteriostatic and anti-scratch film ensures reliable performance in these challenging environments, helping farmers maintain optimal oxygen levels to prevent fish stress, suffocation, and disease. By providing real-time data, it enables proactive management of aeration systems, enhancing aquatic health and improving aquaculture efficiency.
This model is particularly suited for large-scale fish farms, shrimp hatcheries, and aquaculture research facilities, where accurate and durable monitoring is critical for sustainable production. Its robust design and advanced technology make it a trusted solution for ensuring water quality and maximizing yield in intensive aquaculture operations.
②Wastewater Management:
Tracks oxygen levels in industrial or agricultural runoff with high particulate content.
③Research and Environmental Monitoring:
Ideal for long-term studies in challenging natural water bodies, such as estuaries or polluted lakes.
