Hyper-Spectral Absorption Instrument

Hyper-a full view View Gallery

In-situ absorption meter based on the integrating sphere principle.

The Hyper-a is designed for precision, in-situ bulk absorption measurements of dissolved and suspended material in water. A removeable ND filter in the cavity wall can be used to track instrument drift, eliminating the need for sending the instrument back for factory calibration.

Features

  • High precision absorption measurements
  • High-performance depth and temperature sensors.
  • Internal data storage.
  • Powered from external battery pack (optional accessory), CTD, or up to 50 m power/communication USB cable.
  • Up to 3 spectral filters for correcting for phytoplankton and other fluorescence.
  • Included SeaBird pump (SBE-5P)
