Y4000 Online Multiparameter Sonde
Yosemitech Y4000 multi-parameter sonde features an integrated multi-in-one structural design. Each individual probe is an RS485 digital probe with calibration data stored directly in the single-parameter sensor. This allows for easy on-site calibration or replacement of each probe. The sonde supports online monitoring of multiple parameters, including temperature, pH, ORP, DO, conductivity, turbidity, chlorophyll, BGA, OIW, salinity, and depth. The main body can connect up to six probes, enabling simultaneous detection of seven parameters. Additionally, the Y4000 is equipped with a self-cleaning brush that effectively cleans the measurement surface, removes bubbles, prevents microbial attachment, and ensures reliable performance across various water environments, such as wastewater treatment, surface water, oceanic, and groundwater monitoring.
- RS485 output with standard MODBUS protocol, facilitating seamless integration between data acquisition platforms and water quality automatic monitoring stations.
- The main body supports connection to up to six probes for parameters such as DO, conductivity (salinity), turbidity, pH, ORP, chlorophyll, BGA, OIW, and depth.
- Equipped with a self-cleaning brush for scheduled cleaning at predefined intervals, minimizing errors caused by bubbles or contamination.
- Each probe can be individually replaced, calibrated, and maintained on-site, offering flexibility and convenience.
- Features an efficient acquisition algorithm with a system-wide response time of ≤30 seconds.

Sewage and Wastewater Treatment:
Continuous monitoring of effluent quality to ensure compliance with environmental regulations.
Optimization of treatment processes based on real-time data.
Surface Water Monitoring:
Monitoring lakes, rivers, and reservoirs for pollution, eutrophication, and other environmental concerns.
Supporting environmental research and management.
Oceanographic Studies:
Studying marine ecosystems by monitoring water quality parameters.
Detecting oil spills and monitoring algal blooms.
Groundwater Monitoring:
Ensuring the safety and quality of groundwater for drinking purposes.
Monitoring the impact of agricultural and industrial activities on groundwater.
Industrial Applications:
Monitoring process water in various industries to ensure it meets quality standards.
Managing cooling water systems to prevent issues like scale, corrosion, and biological growth.
Aquaculture:
Ensuring optimal water quality in fish farms to promote healthy fish growth.
Monitoring harmful algae that can affect aquatic life.
Municipal Water Supply:
Ensuring safe drinking water by monitoring water quality from source to tap.
Detecting and addressing contamination issues in the distribution system.
Environmental Impact Assessments:
Providing baseline data for environmental impact assessments.
Ongoing monitoring to detect changes due to project implementation.
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.
