Differential Membrane 0.2mm

For high frequency ultrasound pressure measurements, where the minimisation of spatial averaging is important, this membrane is recommended.


16 micron 0.2mm Membrane Hydrophone – Order Code D1602

12 micron 0.2mm Membrane Hydrophone – Order Code D1202

This hydrophone must be used in deionised water. It is supplied with its own power supply and has a 50 Ohm output.

* Precision Acoustics reserves the right to change the specification without notice. Warranty: membranes 12 months against defective product but not damage caused by user. If a warranty claim is made on devices that have been calibrated at NPL, London, a charge will be made for the used part of the calibration (e.g. in the event of failure of a membrane at three months the charge for recalibration at NPL is 25% of the calibration charge).
