The Cetacean Research™ C54 series of hydrophone has been replaced by the C55 series. The following has been retained for reference. See the C55 page for details.
The Cetacean Research™ C54XR and C54XRS models are preamplified, cylindrical hydrophones designed for the detection of infrasonic, audible, and ultrasonic sounds. In addition to typical underwater use, these hydrophones can also be used for the detection of airborne and subterranean sounds and vibrations. The C54XR and C54XRS hydrophones include an integral connector and are encapsulated in a very rugged polyurethane material. The hydrophones are not individually calibrated but calibrated frequency response measurements can be performed on request.
Shielded Cable Length [m]
- mating connector molded to 15, 30, or 50 [m] shielded cable
- other lengths available on a custom order basis
- cable includes Integral Connector rated to a depth of 7,000 meters.
