Broadband measurement hydrophone

The AS-1 is designed to provide maximum sensitivity in a small size while also providing a linear response in the bandwidth of the highest-quality commercial digital sound recording interfaces. Response is omnidirectional in the human auditory bandwidth, as well as omnidirectional in the horizontal axis at all frequencies (theoretical). Given these qualities, the AS-1 is well-suited for absolute underwater sound measurements in marine and industrial environments. It can also be used as an omnidirectional reference projector.

Use directly with your scope or DAQ device (we deliver the DAQ200) or use with the PA4 preamp and any digital recorder or sound interface for high-quality, low-cost underwater sound analysis.  Fitted, breathable EVA case included with cable lengths of 20 meters or less (longer cable assemblies will not fit in case and will be bulk shipped in allowable packaging).
