High-Performance Self-Contained Hydrophone
This product integrates a high-sensitivity hydrophone, ultra-low-noise analog conditioning circuit, 24-bit high-resolution digital quantization unit, data storage unit and rechargeable high-capacity lithium-ion battery pack. It enables continuous acquisition of underwater acoustic signals across the full frequency band of 8 Hz to 80 kHz for up to 60 days.
The full product series adopts titanium alloy construction. Featuring compact dimensions, it supports acoustic applications at full-ocean depths down to 6000 m.
### Two Variants Available
**LN (Low Noise) Variant**
- Sensing frequency band: 8 Hz to 40 kHz
- Minimum equivalent self-noise lower than ocean ambient background noise
- Suitable for ocean environment surveys and far-field acquisition
- Uses omnidirectional spherical hydrophone
- Three software-configurable signal amplification gain settings
**HF (High Frequency) Variant**
- Operating range: 20 Hz to 80 kHz
- Minimum equivalent self-noise: 28 dB re μPa²/Hz@10 kHz
- Maximum sampling rate: 200 ksps
- Applicable to nearly all marine underwater-acoustics applications
