Product Overview
The BBUA-H100K is a 5–100 kHz wideband hydrophone for underwater acoustic reception. It integrates a 40 dB preamplifier and provides omnidirectional response. Its upper frequency limit reaches 100 kHz, making it suitable for marine oil and gas exploration, seabed mapping, pipeline leak detection, geological prospecting, and general underwater acoustic monitoring.
