• Smooth Operation: Vibration-free and smooth operation for accurate results.

The Copper Corrosion test is a widely used oil analysis method for gearbox, turbine and hydraulic lubricants. This oil analysis method will detect the corrosive effects of a lubricant on copper alloys, but it is ineffective on iron or ferrous alloy parts and components. The copper corrosion oil analysis method, ASTM D130, is relatively simple. A polished copper strip is immersed in 30mL of sample at elevated temperature, 50 °C or 100° C, depending on the type of gasoline, grease or oil
