HydroRad Hyperspectral Radiometers

Full-spectrum, high-resolution data

HydroRad measurements of downwelling  irradiance (Ed) and upwelling radiance (Lu)

HydroRads are complete radiometric measurement systems, ready to immediately provide full-spectrum, high-resolution measurements in air or under water at depths up to 200m.


Different HydroRad models (listed below) provide from 1 to 4 simultaneous measurement channels.  You choose the number and types of light collectors to be installed, and whether the collectors are embedded directly in the instrument or mounted on flexible fiber optic cables.


All HydroRads include an intelligent programmable data logger/controller, and internal rechargeable batteries are standard, for fully autonomous operation.  Of course you can also collect data in real time on your laptop with the supplied Windows software.
