C55 series of hydrophones are preamplified, cylindrical hydrophones designed for the detection of infrasonic, audible, and ultrasonic sounds. Please note these hydrophones are available by special order only. For nearly all applications, we recommend using the C57-series hydrophones instead.
In addition to typical underwater use, the Cetacean Research™ C55 series hydrophones can be used for the detection of airborne and subterranean sounds and vibrations.
The C55, C55RS, and C55X hydrophones include an integral connector and are encapsulated in a very rugged polyurethane material. An extra-rugged version is now available: the Cetacean Research™ C57 hydrophone.
The hydrophones are not individually calibrated but calibrated frequency response measurements can be performed on request.
