Founded in 2017 and located in Weifang, Shandong, Shandong Fengtu is dedicated to the research, development, production, and sales of water quality monitoring equipment. Its products cover sensors and online monitoring systems for pH, conductivity, dissolved oxygen, turbidity, BOD, and COD, widely used in environmental protection, water management, and aquaculture.
Water quality sensors are the core components of online water quality monitoring systems, and their performance directly determines the accuracy of monitoring data and the stability of system operation. Shandong Fengtu IoT Technology Co., Ltd. is a water quality sensor manufacturer integrating R&D, production, sales, and service. Founded in 2017 with a registered capital of 10 million yuan, the company is headquartered in Weifang High-tech Zone, Shandong Province. The company possesses a complete production chain, technical team, and marketing team. Its product line covers the main sensor types in the water quality monitoring field, including pH sensors, conductivity sensors, dissolved oxygen sensors, turbidity sensors, suspended solids sensors, BOD sensors, and TDS sensors.
In terms of technical parameters, the water quality sensors produced by the company have high measurement accuracy and reliability. The water temperature sensor has a measurement range of -50 to 80℃, a resolution of 0.1℃, and an accuracy of ±0.5℃; the conductivity sensor has a range of 0 to 200 mS/m, a resolution of 0.2 mS/m; the pH sensor has a range of 0 to 14, a resolution of 0.01 pH, and an accuracy of ±0.1 pH; the dissolved oxygen sensor has a range of 0 to 20 mg/L, a resolution of 0.1 mg/L, and an accuracy of ±3%. The turbidity sensor has a range of 0.1 to 3000 NTU. The water quality TDS sensor has an IP68 waterproof rating, uses an RS485 digital interface, and supports the MODBUS protocol, allowing for direct immersion in water for long-term operation. The BOD sensor uses optical measurement principles, enabling real-time monitoring of biological oxygen demand in water without complex pretreatment.
In terms of water quality monitoring system integration, this manufacturer has developed multiple online water quality monitoring devices and systems based on its independently developed water quality sensors. Pole-mounted online water quality monitoring systems use water quality sensors as their core. By monitoring and analyzing various water quality parameters, the collected data is transmitted to a cloud platform, enabling remote viewing of real-time data and equipment management. It also provides alarms and intelligent processing for exceeding water quality limits. Buoy-type water quality monitoring equipment uses a 360° circular buoy platform. Underwater, it can carry nutrient, ADCP, and various water quality sensors; above water, it can install multi-parameter meteorological and GPRS communication systems. Collected parameters include pH, dissolved oxygen, conductivity, ammonia nitrogen, nitrate, turbidity, COD, chlorophyll, and cyanobacteria. Drainage network water quality monitoring systems deploy sensors at various nodes in the network to acquire real-time basic data such as water temperature, conductivity, and turbidity, as well as pollutant indicators such as COD and ammonia nitrogen. Once water quality anomalies occur, the system can accurately locate the pollution source using positioning technology.
In industry applications, water quality sensors are widely used in environmental protection, water affairs, municipal administration, aquaculture, agriculture, water conservancy and hydropower, and scientific research. The water quality sensors and monitoring systems provided by this manufacturer are suitable for diverse scenarios such as rivers, lakes, reservoirs, groundwater, waterworks, sewage treatment plants, and aquaculture farms. They support both solar power and 220V AC power, and utilize the MQTT protocol to connect to an IoT cloud platform. Real-time and historical data can be directly observed via mobile phones and PC browsers. With the increasing national emphasis on water environmental protection and the ongoing development of online water quality monitoring networks, the fundamental role of water quality sensors in smart water management and ecological environment monitoring will become increasingly prominent.
