③ Reliable Performance: Maintains high accuracy (±0.3mg/L) and consistent operation within a wide temperature range (0-40°C), with a built-in temperature sensor for automatic compensation.
④ Low Maintenance: Eliminates the need for electrolyte replacement or frequent calibration, reducing operational costs and downtime.
⑤ Easy Integration: Supports RS-485 and MODBUS protocol for seamless connectivity with existing monitoring systems, compatible with 9-24VDC power supplies for flexible installation.
Application
Aquaculture 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.
Wastewater Management:
Tracks oxygen levels in industrial or agricultural runoff with high particulate content.
Research and Environmental Monitoring:
Ideal for long-term studies in challenging natural water bodies, such as estuaries or polluted lakes.
