Copper strip corrosion testing is widely used to determine the presence of corrosive sulfur compounds in fuels and lubricants. During the test, a polished copper strip is immersed in the petroleum sample and maintained at a specified temperature for a defined period. After the test, the copper strip is compared with the standard corrosion classification chart to determine the corrosiveness of the sample.

This Copper Strip Corrosion Analyzer adopts a metal bath heating system, eliminating the need for traditional water baths and providing more stable and reliable temperature control. The system integrates precise temperature control, automatic timing, and alarm functions, ensuring accurate and efficient copper corrosion testing.

The instrument is widely used for evaluating the corrosion characteristics of petroleum products such as aviation gasoline, aviation turbine fuel, automotive gasoline, kerosene, diesel fuel, solvents, and lubricating oils.

The Copper Strip Corrosion Analyzer is suitable for testing:

• Aviation gasoline
• Aviation turbine fuel
• Automotive gasoline
• Diesel fuel
• Kerosene fuels
• Solvent oils
• Lubricating oils

Typical application environments include:

• Petroleum refineries
• Fuel testing laboratories
• Aviation fuel quality inspection laboratories
• Lubricant manufacturers
• Research and testing institutions

The instrument uses a metal bath heating system instead of a traditional water bath, providing stable temperature control and easier operation without the need for water circulation.

An 8-inch color touchscreen (800 × 600 resolution) provides clear display of temperature, time, and test parameters with menu-guided operation.

The microcontroller-based temperature control system allows adjustable temperature from room temperature to 200°C with high precision of ±0.1°C.

An A-class PT100 temperature sensor ensures high measurement accuracy and excellent stability.

Heating components and structural parts are made from stainless steel for corrosion resistance and long service life.

The instrument includes an automatic timer with alarm notification when the preset test time is reached.

The instrument provides four test positions, allowing multiple samples to be tested simultaneously and improving laboratory efficiency.

This Copper Strip Corrosion Analyzer complies with:

• ASTM D130 – Standard Test Method for Corrosiveness to Copper from Petroleum Products
• GB/T 5096 – Copper Strip Corrosion Test for Petroleum Products
• ISO 2160 – Petroleum Products Corrosiveness to Copper Test
• IP 154 – Determination of Corrosiveness to Copper
