PASSIVATION TEST FOR STAINLESS STEEL

Passi Test Plus is a tool designed to assess the real quality of the stainless steel. It consists of a “probe pen” that contains the electro-chemical solution and of an external storage unit. By pressing the probe pen on the surface, Passi Test Plus measures the open-circuit potential and the nobility of a metal thus measuring its corrosion resistance.

The test, which is non-destructive and non-damaging, is fast (the result is given in 15 seconds) and numerical: while the other passivation tests, purely chemical, are based on the interpretation of a colour (ferrocyanide test), thus offering a strongly subjective datum, often distorted by superficial impurities, Passi Test Plus releases an exact and , indisputable numerical value.
