Versatile Operates as a Directional Wave Gauge, a Tide Gauge, or as a combination instrument, simultaneously sampling both of these parameters.
Accurate The sensor suite is a recognized industry standard:
     
    (3) Paroscientific DigiQuartz pressure sensors: 
    - 0.015% FS accuracy (1 cm for 100 psi w/ temperature compensation)
    - 0.0015% FS resolution (1 mm for 100 psi range)
    KVH digital fluxgate compass
    Optional: Conductivity sensor SBE-4
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.
