Onda - Model HM-Series - Membrane Hydrophone - Datasheet

The HM Series membrane hydrophones are designed for measuring pulsed ultrasound fields. Their extremely flat sensitivity results in the best reproduction of acoustic waveforms. Version A is the traditional hydrophone configuration, and a more rugged version B prevents membrane vibration during scanning motion. Version A is recommended for high power ultrasound work, where the absorption of energy by the backing could result in damage to the hydrophone. Both types are excellent choices as in-house primary or secondary standard, and for general purpose field mapping.
