The Cetacean Research™ C55 and C55RS 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 C55 and C55RS 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.
