Hannas - Model PZT5A -Piezo Ceramic Plate Transducer for Hydrophone

Hydrophones are individually calibrated, waterborne-sound transducers. The instruments deliver a flat frequency response and are omnidirectional over a wide frequency range. All hydrophones are built with a shielded-element construction; completely waterproof, corrosion-resistant, and are able to withstand high levels of salinity. The instruments provide unrivaled depth, range, and precision when measuring sound in the lab and in ocean research.
