Introduction

Yosemitech Y4003 Online Multi-parameter Water Quality Sensor adopts a robust, pressure-resistant design and a proprietary titanium alloy watertight connector, making it ideal for marine environment monitoring, deepwater wells, and similar applications. The main unit is equipped with six uniformly designed sensor interfaces, allowing the installation of up to six sensors. Users can choose from a variety of sensor options, including dissolved oxygen, pH/ORP, conductivity (salinity), turbidity, chlorophyll, blue-green algae, oil in water, depth, and more. Each sensor operates using its specific optical, electrochemical, or physical detection principle to measure corresponding parameters.

In addition to the 6 sensor interfaces of uniform specifications, the interface in the center of the mother body is used to install a cleaning brush, which can effectively clean the measuring end face, scrape off bubbles, and prevent microbial attachment. The Y4003 can withstand up to 20bar water pressure and work stably, and can easily cope with the monitoring needs of various water environment conditions such as marine monitoring, deepwater lakes, underground drilling, and harsh wastewater.

Parameter

Usage Environment

High-pressure deep-water environment: Suitable for environments with water depths of tens to hundreds of meters. The sensor housing is made of high-strength pressure-resistant materials (such as titanium alloys and engineering plastics) to ensure that it does not deform or leak under high pressure.

Complex water quality conditions: It can be used in a variety of water bodies such as seawater, fresh water, and sewage. The corrosion-resistant design (such as anti-salt spray coating) adapts to high salinity, acidic or alkaline environments.

Wide temperature range: The operating temperature range is wide (such as -5℃ to 50℃), and the built-in temperature compensation module ensures data accuracy in low temperature or drastic temperature difference environments.

Biological contamination risk area: In eutrophic waters or oceans, the sensor surface may face problems with algae and shellfish attachment. Yushan seven-parameter marine integrated sensor is equipped with anti-biological contamination coating or self-cleaning structure.

Long-term unattended scenarios: Suitable for deep-sea observation stations, reservoir monitoring buoys and other occasions that require long-term continuous monitoring. The design is low power consumption and supports remote data transmission.

Advantages of Deepwater Sensors

-Multi-parameter integrated measurement: The seven-parameter marine integrated sensor can simultaneously detect parameters such as pH, dissolved oxygen (DO), conductivity (EC), oxidation-reduction potential (ORP), temperature, etc., reducing deployment costs and complexity.

-High precision and fast response: The electrodes are in direct contact with the water body, providing real-time feedback on water quality changes, with a short response time (such as dissolved oxygen detection can be completed within seconds), suitable for dynamic monitoring.

-Strong pressure resistance and durability: The sealing process and pressure-resistant structure are adopted to ensure long-term stable operation under deep water and high pressure; corrosion-resistant materials extend service life.

-Low maintenance requirements: The sensor is equipped with a cleaning function to reduce manual intervention, suitable for remote or difficult-to-maintain scenarios.

-Wide adaptability: RS485 data interface, which can be integrated into the Internet of Things system or unmanned submersible (ROV/AUV), suitable for scientific research, environmental protection, aquaculture and other fields.

Precautions of Using

Regular calibration is required (especially after long-term continuous use) to maintain accuracy.

Shielding measures are required in strong electromagnetic interference environments.

Manual regular maintenance is still required when biological attachment is severe.
