WET Labs Absorption and Attenuation Meter

The Absorption and Attenuation Meter (ac-9) is an in situ water-based spectrophotometer made by WET Labs, Inc. It measures water's attenuation and absorption simultaneously across a spectral range of 412-715 nm. It can operate at depths up to 500 or 5000 meters and has a nominal sample rate of 6 Hz.
