HYDROPHONES
C57, C57S
C57 hydrophone series is an extra rugged version of C55 hydrophone which is available by special order only; with a shape that allows it to be towed behind a boat with less flow noise. The C57 utilizes a slightly softer polyurethane encapsulation material than the C55, which results in even better underwater acoustic performance. The hydrophones are not individually calibrated but calibrated frequency response measurements can be performed upon request. Battery / Connector box Battery boxes are rated NEMA-4X water resistant. Standard ...
C75
C75 is a preamplified, spherical hydrophone designed for the detection of low frequency, audible, and ultrasonic sounds. C75 Hydrophone has an omnidirectional receive pattern with very wide frequency response for monitoring up to ultrasonic signals. The connector is an integral part of the hydrophone. Hydrophones are not individually calibrated but calibrated frequency response measurements can be performed on request. Battery / Connector box Battery boxes are rated NEMA-4X water resistant. Standard signal connection for the Ceta...
C305
C305 hydrophones have a directional receive pattern with very wide frequency response for monitoring ultrasonic signals not detectable by competing brands. The connector is an integral part of the hydrophone. Hydrophones are not individually calibrated but calibrated frequency response measurements can be performed on request. Battery / Connector box Battery boxes are rated NEMA-4X water resistant. Standard signal connection for the Cetacean Research C305 hydrophone is through a watertight female BNC connector. The hydrophones are...
CR1A
CR1A hydrophone is an excellent multi-purpose hydrophone. Used for detection & recording of loud signals, listening & recording of quieter sounds like cetaceans, whale watching operations. CR1A hydrophone is not pre-amplified. CR1A matches perfectly with any of our DAQ modules. All CR1A hydrophones are individually spot calibrated at the factory.

CR2
CR2 hydrophone is ideal for the detection and recording of loud underwater 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 CR2 hydrophone transducer is made from a material that is virtually indestructible. The hydrophones are molded to an extra tough polyurethane-jacketed coaxial cable. The cables can be terminated with either BNC or mono phone plug connectors. CR2 matches perfectly with any of our DA...
CR3
CR3 hydrophone is an omnidirectional hydrophone with no integrated preamplifier. CR3 matches perfectly with any of our DAQ modules. CR3 Hydrophone
C56
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 inc...
C55, C55RS
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 c...
SQ26-01
The Sensor Technology SQ26-01 hydrophone is a reliable, low cost, rugged hydrophone which is integrated into instrumentation. The SQ26-01 hydrophone is commonly used in towed arrays, AUVs, and autonomous recorders. This hydrophone is very popular with student AUV competition teams. The usable response (+3/-12dB) is good to better than 50kHz. The official "Flat" frequency response (±1dB) is rated to 28kHz. See the frequency response plots and the beam pattern plots (click on any thumbnail for enlargements). Although the...
CRT-40P
CRT-40P hydrophone is powered by the plug-in power feature of the Zoom H1n digital recorder or other similar means of power that is 2.4 V to 5 V.
