CR2 Hydrophone

CR2 Hydrophone

The Cetacean Research™ CR2 hydrophone is ideal for the detection and recording of extremely loud signals.

Examples of such loud sources include close-range dolphin echolocation, high-power sonar, large pile drivers, air gun arrays, and underwater explosions.

Unlike most hydrophones, the Cetacean Research™ CR2 hydrophone transducer is made from a material that is virtually indestructible. The hydrophones are molded to an extra tough, flexible coaxial cable. The cables can be terminated with either BNC or mono phone plug connectors.

Hydrophones are not individually calibrated. Calibrated frequency response measurements can be performed on request.
