Sangari's chemical-engineering apparatus supports the teaching of materials corrosion and electrochemistry. The CH561 stand runs controlled galvanic and electrochemical corrosion experiments on metal specimens in different electrolytes, with direct measurement of corrosion current, potential, and mass loss over time. Useful for teaching corrosion mechanisms, passivation, and the protection strategies — cathodic protection, sacrificial anodes, coatings — that follow from them.
