Yosemitech Y4002 multiparameter water quality sonde features a compact, fully integrated design that enables concurrent real-time measurement of seven key water quality parameters. Its integrated automatic cleaning brush actively mitigates sensor fouling, dislodges entrapped air bubbles, and suppresses biofilm formation—thereby preserving measurement integrity and ensuring long-term operational stability. The sonde is validated for deployment across diverse monitoring environments, including aquaculture facilities, municipal and industrial wastewater treatment plants, surface water bodies (e.g., rivers and lakes), and groundwater wells. Supported by extensive field validation and iterative engineering enhancements, the system delivers exceptional long-term reliability and robust performance under continuous unattended operation.

- 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.
