Tritech PA200 / PA500 – Digital Precision Altimeters

Tritech PA200 and PA500 Digital Precision Altimeters are based on the same high performance electronics found in the well-proven, industry standard Tritech SeaKing sonar and profiler systems.



Full digital synthesis of transmit and receive frequencies with greatly improved input dynamic range.

Tritech’s digital precision altimeters offer configurable design with a wide range of options available. OEM configurations include low magnetic signature rigid Delrin™ (Plastic) housings or supplied with a right-angled transducer.

Control of the altimeters may be performed in many ways including:

  • Altimeter direct from a PC running DOS
  • Altimeter direct from a PC running Windows
  • Altimeter direct from a suitable control system
  • Altimeter as part of a multidrop network
