The HTD-62 Deep-sea Spherical Hydrophone adopts a high-strength spherical structure design, specially designed for extreme high-pressure environments in the deep sea. It has passed the 60MPa (about 6000 meters working depth) pressure test certification and has excellent reliability and durability. This product uses high-performance spherical piezoelectric ceramic components and can be paired with a 10-40dB preamplifier to cover a wide frequency range of 10Hz-200kHz, achieving 360 ° omnidirectional acoustic response. HTD-62 has the characteristics of low background noise, compressive stability, and full frequency sensitivity, making it an ideal acoustic detection device for deep-sea resource exploration, marine environment monitoring, underwater acoustic communication, and other fields.
