Industrial applications such as : 

Metallurgical, mining, paper-making, shipbuil-

ding, nuclear, environmental and mechanical, food 

industry (see our list of approvals).

  •  For special applications, especially for parti-

cularly difficult media, contact our technical 

back office team.

  •  For vacuum and frequencies above 1 cycle / 

min, the headline will be pasted.
