HydroScat-2 Backscatterometer-fluorometer
HydroScat-2
Shown with optional
anti-fouling face plate
The HydroScat-2, HydroScat-2 Abyss, HydroScat-4 and HydroScat-6 are literally and figuratively the First Family of multi-wavelength optical backscattering sensors: not only the first in the world, but also preeminent in performance.
