Corrosion test cell

Claim 1

A corrosion test cell assembly suitable for determining the electrochemical corrosion parameters of metals in corrosive liquid environments comprising; a. an electrically non-conductive vessel for receiving an electrolyte solution, b. an electrically non-conductive cover member adapted to be secured to said vessel, c. a plurality of metallic rods supported in said cover member in electrical isolation, both ends of said rods extending axially from said cover member, one end of each rod having terminal connector means thereon and supported within said vessel, the other end of each of said rods being connectable to suitable electrical conducting means, one of said rods being centrally located in said cover member, the remaining rods being arranged symmetrically around said central rod, d. a reference electrode secured to said terminal means of said centrally located rod and adapted to be supported within an electrolyte solution in said vessel, e. at least one of said terminal means of one of the remaining rods adapted to secure a test electrode thereon and supportable within an electrolyte solution in said vessel, f. an auxiliary electrode surrounding said reference electrode and said metal rods, g. insulating fluid seals encircling said terminal means and adapted to be engaged in fluid tight relationship between said terminal means and electrodes secured thereon, h. said electrical conducting means providing circuits with said electrodes during said determination of electrochemical corrosion parameters.
