Model A1280 Mechanical Impurity Tester is applicable for determining the content of mechanical impurities in various light‑weight and heavy‑weight oils, lubricating oils and additives of petroleum products. It is widely used in electric power, petroleum, chemical industry, commodity inspection and scientific research departments.

The instrument is widely used for quality inspection, production control and laboratory analysis in:

• Petroleum refineries
• Lubricant manufacturers
• Chemical industries
• Power plants
• Scientific research institutes

Working Principle

The A1280 adopts the filtration and gravimetric measurement method.

Testing procedure:

Step 1

The petroleum sample is heated and mixed with solvent.

Step 2

The sample passes through a standardized filter membrane.

Step 3

Mechanical impurities remain on the filter.

Step 4

After drying and weighing, the impurity content is calculated.

The result reflects the cleanliness level of the petroleum product.
