HP 0.5mm Interchangeable Probe - Order Code HPM05/3

All dimensions 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
Hydrophones of 0.5mm have been widely used in the measurement of high frequency ultrasound. With the exceptional signal-to-noise ratios obtainable from the HP series of probes, Precision Acoustics would recommend the use of this device for measurements where signal amplitudes are expected to be particularly low.
Specification
