Product Introduction
Our online multi-parameter sensor adopts a multi-in-one structural design. Each single-parameter sensor is a RS485 digital probe that is water-tightly connected to the mother body, and the calibration data is stored in the single-parameter sensor, which can be easily calibrated or replaced on site. It can monitor the conventional 5 parameters of water quality (water temperature, pH/ORP, dissolved oxygen, conductivity, turbidity) online, and can also monitor chlorophyll, cyanobacteria, oil in water, and the maximum number of mother bodies that can be connected is 6, detecting up to 7 parameters.
The online multi-parameter sensor comes with a cleaning scraper that can effectively clean the measurement surface, remove bubbles, and prevent microorganisms from adhering. It can easily handle the monitoring needs of various water environmental conditions such as sewage treatment, surface water, ocean, and groundwater. After years of market application and technical iteration, the sensor as a whole has excellent reliability and can run unattended for several months without maintenance.
Sensor Characteristics
All-digital sensor with RS485 output and standard MODBUS protocol;
All calibration parameters are stored within the sensor. Each probe is equipped with a waterproof connector for convenient plugging and unplugging as well as replacement;
Equipped with an automatic cleaning device for regular and automatic cleaning, eliminating errors caused by bubbles or contamination on the probe. It is suitable for long-term unattended online monitoring;
The mother body can connect up to 6 probes at most, and sensors such as dissolved oxygen, conductivity (salinity), turbidity, pH, ORP, chlorophyll, cyanobacteria, and oil in water can be freely selected;
Each sensor can be replaced, calibrated, and maintained on-site, offering great flexibility and convenience to users;
High-efficiency collection algorithm. The overall response time of the device is ≤ 30s. The mother body integrates voltage anomaly shutdown, communication anomaly alarm, cleaning brush anomaly alarm, facilitating operation and maintenance judgments.

Yantai Kekan Ocean Technology Co., Ltd. is a technology-based small and medium-sized enterprise that integrates the researchand production of marine observation and monitoring equipment, marine environmental services,and the development of key supporting systems for marine engineering. Adhering to the spirit of "scientfic management and exploration of the deep sea", it focuses on the research and development of intelligent marine observation and monitoring equipment and the safety guarantee of offshore engineering.
The R&D team of the company is led by Professor You Zajin, an academician of the European Academy of Sciences. He has been engaged in research on ocean dynamics, numerical model construction,and has led projects funded by the Natonal Young Scholars Fund, the Ministry of Sclence and Technology's key R&D project, the National Key Fund, and multiple Australian Key Fund projects.The core personnel of the team also include multiple doctoral and high-end managemert talents in the marine field, with complementary professional backgrounds and a solid foundation for cooperation. They have jointy cariedout muliple related projects/research projects and possess the strength of product design, manufacturing, and sales. Since its establishment, the company has applied for more than 30 patents and softworks, of which 13 have been authorized, possessing exclusive intellectual property rights and strong technical barriers.
The company's main products are intelligent marine environmental element observation and monitoring equipment and high-precision early warning and forecasting system, among which the intelligent observation and monitoring equipment has the function of self-positioning, which can adjust the positioning based on real-time sea conditions and relying on low-power power system; The submarine winch has the advantages of small size, strong traction and good sealing, which can better adapt to the complexity of the seabed work; The high-precision marine hydrological element early warning and prediction system provides wave, tide, storm surge and sediment transport data, solves the problems of unclear physical mechanism and low simulation accuracy of current numerical simulaton, and can provide a solid guarantee for marine enginering.
