HYDRO-BIOS MultiNet

the only Multi Plankton Sampler for horizontal and vertical collections. 


Available in now four sizes:

Mammoth

aperture  1,0 m²

Maxi

aperture  0,5 m²

Midi

aperture  0,25 m²

Mini

aperture  0,125 m²


with 5 resp. 9 net bags. All MultiNets are equipped with pressure sensor and 2 electronic flow meters - one inside, one outside of the open area of the frame - to detect clogging in the net bags. MultiNets will be delivered as combined online/offline instruments, so it is possible to use single conductor cable as well as a normal steel wire with preprogrammed changing depth of each single net.

Each MultiNet can be equipped with various sensors - C,T and others - to measure various parameter and refer them to the collected species and depth. Standard operational depth is 3.000 metres,  6.000 metres on request. For detailed information download the new MultiNet prospect
