0.075mm Needle Hydrophone (75 micron)

The 0.075mm needle hydrophone has a good signal-to-noise ratio and we would recommend the use of this device in high frequency, high pressure fields to minimise the effect of spatial averaging.



This product is available to buy direct through our secure online shop.

All dimensions are in mm. All probes are hand made and as such there is always some variation between individual devices. Please contact us if the actual dimensions are critical to your work.
