Sound velocity profiler for underwater mapping & surveying

Visit Website Send Message

The SVP1500 sound velocity profiler provides accurate speed of sound information and depth measurement for a wide range of applications including underwater mapping and surveying and marine construction. With a high sampling rate, advanced time-of-flight measurement technology, and an integrated high-precision pressure sensor, it can measure sound velocity at accuracies of 0.05m/s, and depth at an industry-leading precision of 0.15m.

The lightweight and corrosion-resistant sensor includes a built-in high-performance lithium battery that provides a continuous working life of more than 8 hours, and a storage capacity of 16GB for logging over 4000 hours of data.
