Hydrophone Projector TD0280

The Colmar TD0280 is a mid-high frequency spherical hydrophone / projector, suitable for a wide range of applications. As a receiver the frequency usable limits are 5Hz—90kHz., a pre-amplifier is recommended in order to enhance the S/N ratio and make the cable attenuation negligible. As a transmitter TD0280 offers omnidirectional pattern over the transmission resonant frequency bandwidth.

Omnidirectional, mid-high frequency hydrophone / projector. Usable over a wide frequency bandwidht, up to 90kHz
Suitable for tank and free field calibrations
Sensitivity unaffected by hydrostatic pressure down to the reccomended depth
Custom cable lenght and connector type
