CR3 Hydrophone

C305 Hydrophones

Cetacean Research™ C305 Hydrophones, shielded versions of the Cetacean Research™ C304XR with a tougher encapsulation, are available for purchase.

The Cetacean Research™ C305 series 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.

SQ26-01 Hydrophone

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 SQ26-01 hydrophone is low cost, it is a professional hydrophone and is not recommended for novice users.

The SQ26-01 hydrophone has a 2000m depth rating and is, therefore, subject to export restrictions.

CR2 Hydrophone

The Cetacean Research™ CR2 hydrophone is ideal for the detection and recording of extremely loud 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 Cetacean Research™ CR2 hydrophone transducer is made from a material that is virtually indestructible. The hydrophones are molded to an extra tough, flexible coaxial cable. The cables can be terminated with either BNC or mono phone plug connectors.

Hydrophones are not individually calibrated. Calibrated frequency response measurements can be performed on request.
