More detail

Our high-performance needle hydrophone system consists of a range of interchangeable PVdF needle hydrophone probes, a submersible wide-band amplifier and a DC coupler.

The needle probes are available in a range of diameters from 0.04 mm to 4mm, with film thickness ranging from 9 to 28 µm. Custom versions of hydrophones are available, such as right angle or side facing versions. Please contact us to discuss any special requirements you have.

The L-shaped mount, pre-amp and DC coupler are included with all systems along with a calibration 1 to 30 MHz (0.040, 0.075, 0.2, 0.5 mm) & 1 MHz to 30 MHz (1 mm, 2 mm, 4 mm).

Needle hydrophones

Needle hydrophones 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.
