HydroRad Hyperspectral Radiometers

Choose one for each channel:

• Plane irradiance collector—specify whether optimized for use in air or water
• Radiance collector
• Scalar irradiance collector

For each fiber optic channel, specify cable length of 1 meter or more (note that fiber attenuation may be significant for long cables)

Max Pressure (PSI absolute)	Max. Depth Reading (m)	Resolution (m)	Offset Drift (m)	Max. Safe Depth (m)
50	24	0.01	0.2	65
200	127	0.05	0.7	200
300	195	0.08	1.0	200
None	For surface-use only

• Power/Data Interace cable—10 meters with underwater connector
• PDI extension cable
• Increased logging memory (standard memory holds more than 20,000 full-resolution spectra).
• Shutter port: 2-pin connector for driving anti-fouling shutters
• Integrated anti-fouling shutter (HydroRad-ES1)
• Daisy-chain port: 8-pin connector for interconnecting multiple HydroRads to behave as a unit.
• Deployment Cage
