Application of Smart pH Sensor in Aquaculture

The FST100-PH105 Smart pH Sensor features core advantages of precise monitoring, stable operation and flexible adaptation. It fully meets the demands of all aquaculture scenarios, providing professional water quality monitoring solutions for large-scale pond farming, industrial recirculating aquaculture, cage culture and other scenarios, helping farmers reduce costs, improve efficiency and achieve stable production and income growth.

Maintaining stable pH values is crucial in aquaculture. Most farmed organisms thrive within a pH range of 7.5-8.5. Deviations from this range will cause stress in fish and shrimp, frequent disease outbreaks, and even mass mortality.Adopting the glass electrode method, the FST100-PH105 Smart pH Sensor accurately measures the water potential difference through the coordination of glass indicator electrodes and reference electrodes, enabling real-time online monitoring of pH value and water temperature. With a high measurement accuracy of 0.1 pH, it can accurately capture subtle fluctuations in water pH. Equipped with an automatic temperature compensation function, it effectively eliminates the impact of temperature changes on measurement results, delivering accurate data support for aquaculture decision-making.

Tailored to the particularities of diverse aquaculture scenarios, the smart pH sensor achieves full-scenario adaptation and solves the core pain points of farmers. In large-scale pond farming, its compact size and NPT3/4 pipe thread design allow flexible submerged installation, as well as pipeline and tank mounting without complex construction. It adapts to different monitoring points in ponds and tracks real-time pH changes in water. It provides early warning against gill rot and parasitic diseases caused by acidic water, as well as cyanobacterial blooms and increased ammonia nitrogen toxicity triggered by alkaline water.

In industrial recirculating aquaculture, the sensor supports dual output of 4-20mA and RS485, and is compatible with Modbus/RTU protocol. It can be easily connected to aquaculture control systems such as PLC and DCS to realize remote transmission and centralized management of pH data. It links with water exchange, oxygenation and other equipment to automatically regulate water quality and maintain stable water pH, meeting the precise management and control needs of high-density farming.

For cage culture, greenhouse aquaculture and other scenarios, its IP68 high protection rating and PPS corrosion-resistant shell resist water corrosion and sediment abrasion. It maintains excellent stability even when immersed in water for a long time, eliminating frequent maintenance and reducing labor costs for farmers.

Serving as an "intelligent water quality guardian" for aquaculture, the smart pH sensor adopts a dual high-impedance differential amplifier design, featuring outstanding anti-interference capability and fast response speed. It operates stably in complex aquaculture water bodies and effectively avoids interference from external environments on monitoring data. It is equipped with a 5-meter customizable signal cable to adapt to monitoring requirements of various aquaculture sites, and its 0-4bar pressure resistance range meets the monitoring conditions of all types of aquaculture water bodies.

From pond farming to industrial recirculating aquaculture, and from conventional fish and shrimp farming to characteristic aquaculture, the smart pH sensor safeguards water pH balance throughout the whole process with precise, stable and convenient performance. It helps farmers realize data-driven and intelligent aquaculture, reduce disease losses, improve breeding benefits, and inject technological impetus into the high-quality development of the aquaculture industry.
