Product information

Passi Test Plus is a tool designed to assess the real quality of stainless steel. It consists of a “probe pen”, which contains the electrochemical solution, and an external
storage unit. By pressing the probe pen on the surface, Passi Test Plus measures and stores data on the open-circuit potential and nobility of a metal, thus measuring
its corrosion resistance. The test, which is neither destructive nor damaging, is fast (the result is given in 15 seconds) and numerical: while other, purely chemical passivation tests are based on colour interpretation (ferrocyanide test), thus offering a strongly subjective result that is often distorted by superficial impurities, Passi Test Plus delivers an exact and indisputable numerical value.
