aquatic instruments

For environmental surveys, vertical profiles, coastal monitoring, or remote sensing sea truth, we have:

• PRR Profiling Reflectance Radiometers measures 8 to 19 wavebands of downwelling irradiance and upwelling radiance simultaneously, water temperature, and pressure/depth.  Very wide dynamic range and high speed sampling are important features of this family of instruments.  PRR-800 and PRR-2600.
   
• PUV Profiling UV Radiometer measures downwelling irradiance at 305, 313, 320, 340, 380, 395 nm, and PAR (400-700 nm), water temperature, and pressure/depth.  The highly sensitive UV filter-photodetectors used in the PUV incorporate extremely high out-of-band blocking to minimize errors resulting from spectral leakage.
   
• Natural Fluorometers simultaneously measures scalar PAR (400-700 nm) and natural fluorescence as well as water temperature and pressure/depth to aid researchers interested in phytoplankton ecology and primary productivity.
   
• BIC and BIS Submersible Radiometers measures cosine (BIC) or scalar (BIS) irradiance in 4 wavebands, plus water temperature, and pressure/depth.  Very low power, low cost and over 30 wavelengths to choose from are features of these submersible radiometers.
   
• Single Channel sensors are often used to add individual optical measurements to CTD/STD profilers or for simple monitoring applications.
