Product Introduction
This is a fully refurbished, field-proven portable sound velocity profiler (SVP), a core marine hydrographic survey instrument designed for accurate measurement of seawater sound velocity, temperature, and pressure (depth) profiles. As a leading supplier of pre-owned and refurbished geophysical equipment, we have fully tested, calibrated, and certified this unit to ensure it meets the strict performance standards required for European marine survey, offshore engineering, port construction, and oceanographic research projects.
This SVP system is an essential tool for calibrating multi-beam echo sounders, side-scan sonars, and underwater positioning systems, eliminating sound velocity errors to guarantee the accuracy of underwater topographic surveys. Its compact, portable design makes it ideal for both onshore and offshore field operations, with a rugged stainless-steel probe that withstands harsh marine environments.
