The SPT Series is a compact underwater hydrophone designed specifically for acoustic signal reception. Featuring a robust and specialized mechanical design, it delivers exceptional pressure resistance, enabling reliable operation across a wide range of depths.

With its omnidirectional response and high sensitivity, the SPT Series accurately captures acoustic signals from all directions, making it highly suitable for underwater noise monitoring, distance ranging, and passive acoustic measurements. Built with a high-strength pressure-resistant structure, the SPT Series has been tested to withstand depths exceeding 1000 meters, ensuring stable performance even in demanding deep-sea environments.

In addition, as the design excludes a built-in preamplifier, the unit can also be utilized as a signal transmitter when needed. When integrated with EchoingOcean’s OceanEar acoustic recorders, the SPT Series forms a comprehensive and reliable solution for underwater acoustic monitoring and measurement.
