Yosemitech Y4008 powered multiparameter ecosonde features a built-in lithium battery and storage module, eliminating the need for external power supply and wiring construction. It operates autonomously once deployed in water, greatly simplifying on-site installation processes, reducing the investment in supporting power supply, wiring, and auxiliary materials, and significantly lowering project construction difficulty and long-term overall operational costs. Equipped with a high-capacity battery and low-power architecture, it can operate continuously and stably for over 60 days in conventional sampling mode, providing strong endurance. This makes it perfectly suited for long-term unmanned water quality monitoring scenarios such as rivers, reservoirs, coastal areas, and remote wilderness regions.
The ecosonde adopts a titanium alloy integrated housing, offering exceptional corrosion and aging resistance. It meets the IP68 high-level waterproof rating and can withstand conventional pressure depths of up to 200 meters, making it suitable for harsh corrosive water environments such as deep water, seawater, and industrial wastewater.
It is compatible with Yosemitech full range of multi-parameter sondes, allowing for plug-and-play functionality. With a modular electrode design, on-site installation, disassembly, and replacement can be completed quickly and easily, significantly reducing maintenance difficulty and downtime for maintenance.

- With built-in battery and internal storage, no external power supply is required. Once placed, it can work independently, significantly reducing deployment complexity and operation costs;
- The large-capacity battery combined with low-power design enables continuous operation for over 60 days in regular sampling, suitable for long-term unmanned monitoring in the wild;
- An internal SD card storage device can store up to 150,000 complete data sets, equivalent to over 3 years of continuous monitoring records;
- The titanium alloy shell is IP68 waterproof, with a regular pressure resistance of 200 meters. Its sturdy shell material provides excellent corrosion resistance and pressure resistance performance;
- It is highly versatile, compatible with Yu Shan multi-parameter sensors, ready to use upon connection, and the electrode installation and replacement are quick and convenient.
