French HYDROPTIC company UVP6-LP underwater particle and zooplankton image in-situ acquisition system

Category: Underwater particle and zooplankton image in-situ acquisition system
Model: UVP6-LP
Keywords: Zooplankton image in-situ acquisition system,underwater particulate matter and zooplankton image in-situ acquisition system
Supplier: Technology Co.,Ltd.

UVP6-LP is a small,low-cost version of UVP5. It is designed for low-speed,limited space and low-power carriers,such as profile buoys,gliders,buoys,moorings,underwater robots,etc. UVP6-LP has the same design quality standards as UVP5 and offers resolutions up to 5 million pixels. It can capture focused zooplankton images within the range of the red flash light,with a focusing volume of 0.65 liters. UVP6-LP and UVP5std version and UVP5hd version systems are calibrated against each other.

French HYDROPTIC company - UVP6-LP underwater particulate matter and zooplankton image in-situ acquisition system

The UVP6-LP underwater particle and zooplankton image in-situ acquisition system (CNRS patent) is mainly used to simultaneously study underwater large particles (>80μm) and zooplankton (>700μm),and to measure water particles under known water volumes. and zooplankton were quantified. The UVP system uses traditional lighting equipment and computer-processed optical technology to obtain in-situ digital images of zooplankton,with a pressure-resistant depth of 6000m.

UVP6-LP for Argo buoys

UVP6-LP can transmit real-time particle abundance for each size and grayscale to the carrier and,like UVP5,record images of selected organisms and macropolymers for subsequent offline classification. Future versions will also provide an embedded image classification method for online transmission.

Warning: Due to its low acquisition frequency of 1.3Hz and 300μS flash,UVP6-LP cannot be integrated and used on CTD water collectors.

Compatible with Ecotaxa website (,www.ecotaxa.cn)

Process the pictures by UVP6-LP and upload them to the EcoTaxa website. You can use existing libraries on the website or libraries you have created to automatically identify and classify the pictures. At the same time,the corresponding particle size spectrum can also be drawn according to the filtering conditions. In addition,users can also search and browse areas and projects they are interested in on the website.
