HNR-series Needle Hydrophone

The HNR Series needle hydrophones are excellent sensors for laboratory use in high intensity ultrasonic field mapping, with pinpoint access and good spatial resolution.  Due to their high sensitivity these hydrophones are commonly operated without amplification.

Key Features and Benefits
  • Piezoceramic sensing element
  • Needle shape with low reflection profile
  • High sensitivity
  • Integral cable with BNC connector
  • Various apertures available
