10+ years of experience

Always quick results

Advisory report always included

ISO 9001:2015 & VCA* certified

Quick passivity test of your metal

Oxilyser Testing reveals why materials corrode, even while you’re not expecting it. This can occur for instance when stainless steel is processed in an carbon environment or after welding on carbon steel. We conduct quick and professional oxilyser tests on-site, provided the test surface is accessible. Our free advisory report also specifies how to prevent similar future problems.

Oxilyser Testing is used to determine the passivity of materials. This means checking how likely a chemical element is to react with another chemical element. Determining the passivity of your metal is important, in view of possible high repair or renewal costs afterwards.

  • Quick passivity testing of materials
  • Clear problem identification when confronted with unexpected corrosion
  • Advisory Report always included
  • Always conducted on-site
  • ISO 9001:2015 & VCA* certified

Advantages of Oxilyser Testing

Does a material appear to be corroded, though theoretically this shouldn’t be able to happen? Then Oxilyser Testing is a super quick way to determine your material’s passivity. It is a relatively simple probe, which can be conducted on-site. After testing, you’ll know for sure whether a certain material will or will not corrode, as long as it is applied properly.

Take for instance stainless steel that still corrodes after a pickling treatment. Oxilyser Testing is the perfect way to determine whether its passivity has reached its expected level again.

Unclear about the kind of stainless steel a manufacturer has used? In those cases – as Oxilyser Testing proves to be less suitable then – we generally use OES Analysis or XRF Analysis.
