HydroRad-4 Quad-channel Radiometer System
The HydroRad-4 measures four full-spectrum radiometric quantities simultaneously through fiber-optic cables. Each cable is equipped with the light collector type you specify. The cables allow you to position and orient the light collectors in any way that suits your measurement, or to measure the same quantity at different locations. Like all HydroRad models, it is a completely self-contained measurement system with sophisticated data logging and interfacing capabilities.
