产品介绍
NEEDLE HYDROPHONES
Needle hydrophone are good general-purpose measuring devices. They are available in a wide range of diameters from 4.0 mm down to 0.04 mm. The frequency response of a needle hydrophone is dependent on the size of the active element of the hydrophone and the chart below provides an indication of the frequency range of these devices.

All needle hydrophones need to be used with a preamplifier and a DC coupler (shown below). These are an integral part of the hydrophone system whose primary function is to provide electrical impedance buffering.
