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. The instrument logs all data internally and is externally powered. Optional submersible battery packs available.

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)

FAQ

Can I rent the Hyper-a?

Sequoia does not have a Hyper-a rental unit available.

What light sources does the Hyper-a use?

We use a Xenon arc lamp as the light source. This provides broadband coverage through the UV and VIS ranges with a single source.
