APPARATUS FOR MEASURING THE OPTICAL PROPERTIES OF WATER SAMPLES

摘要

The invention relates to an apparatus for measuring the optical properties of water samples in a pre-determined aquatic zone. The invention includes a submersible probe (11) comprising: sensors (21, 23, 25) for measuring optical properties, particularly absorbance, fluorescence and turbidity; sets of light-emitting elements (31, 33, 35) specifically provided for each of said sensors (21, 23, 25), which are arranged such that an optical path is formed between the emitters and sensors through the water samples; a pressure sensor; and a temperature sensor. The invention also includes a monitoring unit (13) located on the surface and connected by cable or radio to the probe (11), comprising means for receiving data from the probe relating to the measurements taken by the sensors (21, 23, 25) in the aquatic zone and means for displaying and storing said data.
