  ProductsOptical Property Measurement HydroScat-6P Backscattering Sensor - Fluorometer 

HydroScat-6P Backscattering Sensor - Fluorometer



Successor to the original HS-6,

includes integrated deployment cage

NOTE: The HydroScat-6P is now available from Hobi Instrument Services

6-Channel Backscattering sensor and fluorometer

Flag ship of the HydroScat Family, the first commercial multi-spectral backcattering sensor and the first to measure both backscattering and fluorescence, the HydroScat-6 has a long record of superior performance and reliability.  Now upgraded to the HydroScat-6P (Plus).
