High Sensitivity 20hz-20khz Hydrophone with Preamplifier Underwater Projector
Product Description
High Sensitivity 20hz-20khz Hydrophone with Preamplifier Underwater Projector
The hydrophone HBC-20 offers a usable frequency range of 20Hz to 20kHz 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 HBC-20 incorporates an electrostatically shielded highly sensitive piezoelectric element connected to an integral low-noise 40dB preamplifier.The hydrophone HBC-20 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 HBC-20 extremely applicable for laboratory as well as industrial uses.
