Copper Strip Corrosion from Lubricating Grease for Petroleum Testing Equipment

The Copper Strip Corrosion Test Bath for Lubricating Grease is designed to determine the tendency of lubricating grease to corrode copper under static conditions. A polished copper strip is immersed in a grease sample maintained at an elevated temperature for a specified period. After testing, the strip is examined for corrosion and assigned a classification number from 1 to 4 by comparison with the ASTM Copper Strip Corrosion Standards.

The apparatus features an immersion-type circulating water bath that maintains the test jars at the required depth and temperature. Its fully insulated, double-wall stainless steel construction supports consistent temperature control during testing.

Manufactured by Atico Export for reliable copper corrosion testing of lubricating greases and oils in petroleum testing laboratories.
