High dephts require high quality of the materials used and a steady control. 
In Resinex Test Centre deep water floats are always tested for dimensions, weight, net buoyancy and pressure resistance. Net buoyancy is also controlled during the pressure tests. Random traction strength tests are also available.
The Resinex Marine Research Centre hosts four pressure tanks up to 200 bars, two load cells for net buoyancy control and one electronic weight control device.
A PC terminal gathers all the data (weight, pressure, net buoyancy) at one point to give our customers a complete Quality Control Test Certificate.
