The Sound Velocity Profiler is an oceanographic instrument used to accurately measure variations in the speed of sound at different depths in water bodies. The instrument determines sound velocity based on parameters such as temperature, salinity, and pressure, and plays a critical role in hydrographic surveys.

The Sound Velocity Profiler is widely used to improve depth measurement accuracy in multibeam and single beam echo sounder surveys. It is designed with a robust construction suitable for reliable operation in ports, coastal areas, rivers, lakes, and other inland and marine water bodies.
