ZRSTQ-1
Self-contained Hydrophone Underwater Sound Recorder for Ocean Deployments
It is an instrument that can independently collect and store acoustic information. It is composed of an underwater acoustic sensor, a conditioning circuit, an amplification circuit, a storage circuit, etc., and is generally equipped with software. It has technical features such as wide working frequency bandwidth, large working depth range, flexible working mode, long continuous working time, and large dynamic range. It is small in size and suitable for flexible formation. Can work in unattended marine environment for a long time. Its convenient and efficient features can meet a variety of use needs, and it has now become an important tool in scientific research fields such as marine environmental noise research, ocean acoustic layer analysis, geoacoustic parameter inversion, and underwater acoustic channel characteristics research.
