A2012 Copper Strip Corrosion Tester | Petroleum Product Corrosion Testing Instrument

Product Overview

The A2012 Copper Strip Corrosion Tester is a professional laboratory instrument used to determine the corrosiveness of petroleum products on copper strips.

It is widely applied for testing aviation gasoline, jet fuel, automotive gasoline, natural gasoline, solvent oils, diesel fuel, distillate fuels, lubricating oils and other petroleum products.

The instrument evaluates the corrosion level of petroleum products by immersing a polished copper strip into the test sample under controlled temperature conditions, then comparing the discoloration of the copper strip with the standard copper corrosion color chart.

The A2012 copper corrosion tester adopts PID temperature control technology, providing accurate temperature stability and reliable test results. It is suitable for petroleum laboratories, fuel quality inspection centers, refineries, research institutes and third-party testing laboratories.
