The hydrophone BRC-40 offers a usable frequency range of 500Hz to 40kHz and a high
sensitivity relative to its size. It further more provides uniform omnidirectional sensitivities in both horizontal and vertical planes up to high frequencies.The hydrophone BRC-40

 incorporates an electrostatically shielded highly sensitive piezoelectric
element connected to an integral low-noise 40dB preamplifier.
The hydrophone BRC-40 is an excellent transducer for making absolute sound measurements
and calibrations within a broad frequency range. It can also be applied as an omnidirectional reference projector.
The overall characteristics makes hydrophone BRC-40 extremely applicable for laboratory
as well as industrial uses.

• High sensitivity
• Omnidirectional to high frequencies
• Broad banded
• Individually calibrated
