Y4003 Multi-parameter Sonde for Deep Water
Yosemitech Y4003 deep-water multi-parameter sonde features a robust structural design, an in-house developed titanium (Ti) waterproof connector, and is specifically engineered for deep water/well, marine, and other demanding working conditions. The main unit can connect up to six probes, with options including DO, pH, ORP, conductivity (salinity), turbidity, chlorophyll, BGA, OIW, and depth sensors, which can be freely selected based on application requirements. All probes are constructed from titanium, ensuring excellent corrosion resistance.
The Y4003 is equipped with a self-cleaning brush that effectively cleans the measurement surface, removes bubbles, prevents microbial attachment, and ensures stable performance under underwater pressures of up to 200 meters. This makes it suitable for monitoring needs in deepwater lakes, oceanic environments, underground drilling, harsh wastewater treatment, and other mid-to-deep water scenarios.
- RS485 output with standard MODBUS protocol, facilitating seamless integration with data acquisition platforms and water quality automatic monitoring stations.
- The main body includes six standardized probe interfaces and a central interface for the cleaning brush, enabling flexible plug-and-play functionality with Yosemitech probes and automatic identification.
- All calibration parameters are stored within individual sensors, allowing for convenient on-site replacement, calibration, and maintenance.
- The configured probes are all made of titanium, providing high-pressure resistance and reliable operation at depths of up to 200 meters underwater.

Oceanographic Research:
Marine Ecosystem Studies: Measure parameters such as temperature, salinity, dissolved oxygen, pH, turbidity, and chlorophyll to understand marine ecosystems' health and dynamics.
Climate Change Research: Track changes in oceanographic conditions over time to study the impacts of climate change on marine environments.
Deep-Sea Exploration: Collect data from deep-sea environments to discover new species and understand the geology and chemistry of the ocean floor.
Environmental Monitoring:
Pollution Detection: Monitor for pollutants like oil, heavy metals, and chemicals in deep water to detect and address pollution sources.
Water Quality Assessment: Continuously monitor water quality parameters to ensure the health of aquatic ecosystems and compliance with environmental regulations.
Harmful Algal Bloom (HAB) Monitoring: Detect and track harmful algal blooms that can affect marine life and human health.
Fisheries and Aquaculture:
Habitat Monitoring: Ensure optimal conditions for fish health and growth by monitoring parameters such as dissolved oxygen, temperature, and turbidity.
Resource Management: Use data to manage fish stocks and aquaculture operations more effectively, ensuring sustainable practices.
Hydrographic Surveys:
Mapping and Charting: Collect data for accurate mapping and charting of underwater features and seabed topography.
Subsea Infrastructure: Monitor conditions around subsea pipelines, cables, and other infrastructure to ensure their integrity and safety.
Deep Lake and Reservoir Studies:
Ecosystem Health: Study the health and dynamics of deep freshwater lakes and reservoirs by measuring key parameters.
Water Supply Management: Monitor water quality to manage and protect drinking water sources.
pH:
Changes in pH in surface water quality affect the ability of algae to take up oxygen and the sensitivity of animals to food intake.
Conductivity:
mainly measures the electrical conductivity of water and monitors the total ion concentration in the water body. Contains a variety of chemicals, heavy metals, impurities and so on a variety of conductive material total.
Dissolved oxygen:
DO in surface water in addition to the usual water sulfide, nitrite, ferrous ions and other reducing substances consumed, but also by the respiration of microorganisms in the water as well as organic matter in the water by the oxidative decomposition of aerobic microorganisms consumed. Dissolved oxygen is an important indicator for surface water monitoring, and is an indication of whether the water body has the ability to self-purify.
Turbidity:
The turbidity value is a visual reflection of the turbidity of the water body. Turbidity is mainly caused by the insoluble substances in the water, insoluble substances including sediment suspended in the water, corrosive substances, planktonic algae and colloidal particles. Reducing turbidity also reduces bacteria, coliform bacteria, viruses, cryptosporidium, iron, manganese, etc. in the water.
Temperture:
Changes in surface water temperature can have a significant negative impact on aquatic wildlife, affecting biological growth and the rate at which fish and shrimp species feed, as well as the timing and efficiency of their reproduction.
