Model 142 Series

Model 142 Series

Available in multiple frequencies, the 142 SERIES transducers are intended for short range, narrow beam echo-sounding applications. 

The 142 SERIES transducers are designed to be compatible with a wide range of echo-sounder models. 

It is also possible to modify the impedance to match any customer values with a simple factory adjustment to the integral transformer. 

The high impact strength nylon body provides a mechanically robust, corrosion free transducer designed for thru-hull, tank or over-side mounting. 

The 142 SERIES is available with or without acoustic calibration, traceable to National Standards. Transducer impedance can be adjusted to suit customers specification.
