max. depth 6,800m

The Tritech Altimeter is based on the same high performance electronics found in the proven, industry standard SeaKing sonar and profiler systems. The range of compact Tritech Altimeters provide exceptionally accurate height of seabed and subsea distance measurements.

Full digital synthesis of transmit and receive frequencies, together with greatly improved input dynamic range, offer unsurpassed levels of performance from a compact unit. The units can be supplied with simultaneous analogue and digital outputs allowing them to be connected to a wide range of PC devices, data loggers, ROV telemetry systems and multiplexers.
