Yosemitech Y4007 CTD sonde is specially designed for long-term online monitoring, featuring an integrated and compact structure. It enables real-time online measurement of 4 key parameters: temperature, conductivity (salinity), and depth, providing accurate and efficient data support for coastal ecological research.
Adhering to the design concepts of miniaturization, high integration and high performance, the CTD sonde reduces size and weight while maintaining reliable performance. This not only ensures easy installation and deployment, but also supports on-site cleaning, saving both time and cost. Capable of operating stably under water pressure up to 200m, it can readily meet monitoring requirements in coastal waters, groundwater, lakes and reservoirs.
