Overview HydroRad-E1 HydroRad-ES1 HydroRad-E2 HydroRad-1 HydroRad-2 HydroRad-3 HydroRad-4 Software

HydroRad-3 Triple-channel Radiometer System

The HydroRad-3 measures three 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.

 Measurement
Configuration
  • 3 fiber-optic light collectors of your choice
  • Fiber optic cable length: 3m standard, shorter or longer available
  • Calibrated Wavelength Range: 350 nm to 850 nm
  • Pixel Resolution: 0.30 to 0.35nm
  • Automatic exposure control: spectrometer integration time from 21 ms to 20 seconds, depending on light levels.
  • Shipped fully calibrated for absolute radiometric measurements.

Data Logging
  • Sampling control options:
    • Autonomous control by internal real-time clock
    • Manual control by case-mounted switch
    • Real-time control via Windows software
  • 128 MB non-volatile storage holds more than 20,000 full-resolution spectra (larger capacities available for special applications). 
  • Calibration can be applied to data by the HydroRad, or externally on a PC.
  • Variable, programmable sampling rates.
