User instructions:

  • Have stainless steel to be tested in a horizontal position
  • Clip the brass probe onto the 9V battery (not included)
  • Place one drop of electrolyte onto the stainless steel
  • Place NEGATIVE probe into into the drop of electrolyte and the POSITIVE probe onto a clean and dry portion of the stainless steel
  • At the negative probe, the liquid around the probe will be "boiling" slightly and form a colored spot
  • Keep for about 3 seconds
  • If the spot is black - low grade stainless steel (i.e. Grade SS202)
  • If the spot is red-brown (and disappears within in second or two) it is SS304
  • If the spot is red-brown (and stays that way) it is SS314
