Precision Acoustics NH0500：0.5 mm needle hydrophone

0.5 毫米针式水听器

With the exceptional signal-to-noise ratio, we recommend the use of our 0.5 mm needle hydrophone for measurements where signal amplitudes are expected to be particularly low.

凭借出色的信噪比，我们建议使用我们的 0.5 毫米针式水听器进行信号幅度预计特别低的测量。

However, these probes can be used for higher frequency measurements (particularly of very weak signals) but in such situations the inherent directivity and spatial averaging characteristics of a 0.5 mm aperture means that care should be taken in interpreting data.

然而，这些探头可用于更高频率的测量(特别是非常微弱的信号)，但在这种情况下，0.5 毫米孔径的固有方向性和空间平均特性意味着在解释数据时应小心。

All dimensions are in mm. All probes are hand made and as such there is always some variation between individual devices.

所有尺寸均以毫米为单位。所有探头都是手工制作的，因此各个设备之间总是存在一些差异。
