Versatile Operates as a Directional Wave Gauge, a Current Meter, a Tide Gauge, or as a combination instrument, simultaneously sampling all of these parameters.
Accurate The sensor suite is a recognized industry standard:
     
  • Paroscientific DigiQuartz pressure sensor

    • - 0.015% FS accuracy (1 cm for 100 psi w/ temperature compensation)
    - 0.0015% FS resolution (1 mm for 100 psi range)
  • Marsh-McBirney EM current sensor
  • KVH digital fluxgate compass
Easy to Use
  • Set-up & download directly through the endcap
  • Output in ASCII Hex or engineering units
  • Removable memory pack allows quick re-deployment
Data Analysis Optional WavePro Software provides fast analysis and presentation of your data using the MATLAB environment.
