C57
CRT C57 HYDROPHONE The Cetacean Research™ 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. Specifications Linear Freq...
C75
CRT C75 HYDROPHONE The Cetacean Research C75 is a preamplified, spherical hydrophone designed for the detection of low frequency, audible, and ultrasonic sounds. It is omnidirectional. The Cetacean Research 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. Specifications for the C75 ...
C305
CRT C305 HYDROPHONE The Cetacean Research 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. Specifications for the C305 Linear Frequency Range (±3dB) [kHz] 0.012 to 250+ Usable Frequency Range (+3/-12dB) [kHz] 0.005 to 250+ Transducer ...
CR1A
CRT CR1A Hydrophone 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. Specifications Linear Frequency Range (±3dB) [kHz] 0.0002 to 50 Useable Frequency Range (+3/-20dB) [kHz] 0.00002 to 110 (Requires a preamplifi...
CR2
CRT CR2 HYDROPHONE This 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 perfe...
CR3
CRT CR3 HYDROPHONE The Cetacean Research™ CR3 Hydrophone is an omnidirectional hydrophone with no integrated preamplifier. CR3 matches perfectly with any of our DAQ modules. Specifications Linear Frequency Range (±3dB) [kHz] 0.0004 to 77 Useable Frequency Range (+3/-20dB) [kHz] 0.0001 to 240 (Requires a preamplifier with 100M input impedance) Sensitivity [dB, re 1V/µPa] -210 Preamplifier Gain [dB] N/A (no built-in preamplifier) SPL Equiv. Self Noise at 1kHz [dB, re 1µPa] 57 Power Require...

C56
CRT C56 HYDROPHONE Cetacean Research™ 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 subter...
