WETLabs ac-s in-situ spectrophotometer
The WETLabs ac-s in-situ spectrophotometer is based on the ac-9 flow through sensor offering increased spectral resolution of in-situ absorption and beam attenuation. The ac-s can have 80 (+/- 5) wavelength outputs with a range of 400-730 nm. The ac-s consists of a 10 or 25 cm pathlength, a 4nm resolution, an accuracy of 0.001 - 10 m -1 , an operational temperature range of 0 - 30 °C and an operational depth rating of 500 m.
