TDH-63 Shallow Water Spherical Hydrophone

1. Introduction

TDH-63 Spherical Hydrophone offers an omnidirectional response up to 160kHz, combined with excellent acoustic characteristics such as low noise and durability. This makes it highly suitable for a wide range of oceanographic applications.contactus

TDH-63 Spherical Hydrophone can incorporate a built-in preamplifier, which not only amplifies the signal but also allows for normal use with extension cables without sensitivity loss. A built-in filter increases the signal-to-noise ratio by removing unwanted noise signals, thereby preventing signal saturation.
