Function Description

Valeport MIDAS SVP Overview

The MIDAS SVP is a high-precision Sound Velocity Profiler designed for quickly acquiring parameters such as sound velocity, temperature, and pressure in the water column. Its robust titanium alloy casing allows it to operate in depths of up to 6000 meters, making it suitable for oceanographic measurements, acoustic calibration, and deep-sea research applications.

Features

  • Synchronized Sampling Technology:​ All sensors sample simultaneously, ensuring data consistency and high quality.

  • Multiple Sampling Modes:​ Supports continuous, burst, profile, conditional, and delay modes to meet various observation needs.

  • Durability:​ Titanium alloy casing and stainless steel protective frame design, suitable for long-term deployment in harsh marine environments.

  • High Capacity Memory:​ Built-in 16MB memory to store large amounts of high-resolution observation data.

  • Flexible Communication Interface:​ Supports multiple communication protocols for easy data download and real-time monitoring.

Applications

  • Sound Velocity Calibration for Multibeam Sonar Systems.

  • Marine Hydrographic Profiling.

  • Deep-Sea Environmental Monitoring and Research.

  • Underwater Acoustics Research and Applications.
