Hydrophone Projector TD0190

The Colmar TD0190 is an high frequency spherical hydrophone/projector, suitable for a wide range of applications. As a receiver the frequency usable limits are 5Hz—170kHz, a pre-amplifier is recommended in order to enhance the S/N ratio and make the cable attenuation negligible. As a transmitter TD0190 offers omnidirectional pattern over the transmission resonant frequency bandwidth.
