500hz-40khz High Sensitivity Low Noise Hydrophone with Preamplifiers Omnidirectional Reference Projector

     500hz-40khz High Sensitivity Low Noise Hydrophone with Preamplifiers Omnidirectional Reference Projector

The hydrophone STQ-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 STQ-40 incorporates an electrostatically shielded highly sensitive piezoelectric ceramics connected to an integral low-noise 40dB preamplifier.The hydrophone STQ-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 STQ-40 extremely applicable for laboratory as well as industrial uses.
