HP 0.2mm Interchangeable Probe - Order Code HPM02/1
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.
Description
The 0.2mm needle hydrophone is our best selling product. With good signal-to-noise ratios Precision Acoustics would recommend the use of this device in most measurement situations to minimise the effect of spatial averaging.
Specification
| Output Impedance: | 13pF+/- 2pF |
