Standard: DELOS-B

SQ42 is broad band hydrophone offering a wide frequency range and omnidirectional response characteristics in both planes. A spherical element is used in the construction of this hydrophone. These characteristics make the SQ42 ideally suited for underwater calibrations and sound measurements up to 350 kHz. The hydrophone has an integral low-noise 40 dB preamplifier that can drive long cables without distortion.
