C56 modular hydrophones are intended to be connected to as many as five other C56 hydrophones (for a total of 6 channels) on a single cable to form an easy-to-use array. They are an inline version of the Cetacean Research™C55 hydrophone.
These preamplified, cylindrical hydrophones are 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.
C56 hydrophones include two integral connectors each and are manufactured using superior piezoelectric transducers encapsulated in a very rugged polyurethane. The hydrophones are not individually calibrated but calibrated frequency response measurements can be performed on request.
