Y4002 Integrated Multi-parameter Sonde
Yosemitech Y4002 Sonde features a compact, integrated design that enables simultaneous monitoring of 7 parameters. Equipped with an automatic cleaning brush, it removes fouling deposits, eliminates air bubbles, and inhibits microbial growth in real time. This ensures long-term stability and measurement accuracy for online water quality monitoring applications. The sonde satisfies monitoring requirements across aquaculture systems, wastewater treatment, surface water bodies, and groundwater monitoring sites. Backed by years of market validation and continuous technological improvement, the system demonstrates superior long-term reliability. It supports continuous unattended operation with maintenance intervals extending to several months.
- Digital sensor, RS485 output, standard Modbus protocol;
- Supports on-site calibration, adapting to various water quality conditions and further improving measurement accuracy;
- Can be directly immersed in the water for all-weather, uninterrupted online monitoring, simplifying system configuration;
- Equipped with an automatic cleaning system to effectively prevent biofouling and sediment deposition, reducing maintenance requirements and manual cleaning frequency;
- Integrated compact design enables simultaneous monitoring of 7 parameters: DO, pH, conductivity, salinity, turbidity, depth, and temp.

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.
