WP-3 net is similar to the WP-2 but larger. The opening has a diameter of 113 cm (approx. 1 m²) and the conical net bag has a length of 200 cm. Standard mesh size is 1000 µm. Other mesh sizes on request. We recommend a minimum of 200 µm.

The letters in () refer to the schematic to the right:

(A) "Nansen release mechanism" (to be ordered separately) for operating/closing plankton net by a 0,8 kg drop messenger.
(B) Three nylon lines (6 mm diameter) with bridle and snap hook (length: 85 cm).
(C) Ring of AISI 316 stainless steel tubing with 3 loops for bridle and weight lines, 2 loops for an optional digital counter located in the middle of the opening. I.D. Ø113 cm = area of 1,0 m2.
(D) AISI 316 stainless steel clamping fixture.
(E) Part a net: 1000 µm Monodur Nytal (nylon) net with 6 loops for the 6 mm (diameter) nylon line closure rope. Cylindrical net length is 95 cm. Part b net is identical to a, but conically shaped. The length is 200 cm.
(F) AISI 316 stainless steel clamping fixture.
(G) Net bucket, based on the Hensen design. The bucket is made of a Polypropylene tubing, diameter 160 mm, with a plastic draining tap, 6 openings, (Total area of 315 cm²), covered by a AISI 316 stainless steel net (mesh size similar to the main net), 1 round supporting rack bucket and 3 loops for lead weights.
(H) 3 Nylon lines for the weight with bridle and snap hook.
(I) Lead weight of 25 kg (11 weights of 2 kg, mounted in a 3 kg rack).
