Product Overview
The A1081 Lubricating Oil Foam Characteristics Tester is a high-precision petroleum laboratory instrument specially designed to determine the foaming tendency and foam stability of lubricating oils under standardized test conditions. Excessive foam in lubricants can reduce lubrication efficiency, accelerate oxidation, cause pump cavitation, and increase wear of mechanical systems. Therefore, foam characteristic testing is an essential quality control procedure for lubricant manufacturers, refineries, industrial plants, and testing laboratories.
The A1081 is fully developed according to ASTM D892 and GB/T 12579 standards, ensuring globally recognized and repeatable test results. The instrument uses advanced temperature control technology, accurate airflow regulation, intelligent timing systems, and a stable air supply unit to provide precise foam measurement across multiple temperature stages.
Designed for modern laboratories, the A1081 combines user-friendly operation, durable construction, and reliable testing performance. It is widely used for evaluating turbine oils, hydraulic oils, compressor oils, engine oils, and other industrial lubricants where anti-foam performance is critical.
Whether for routine quality inspection, production control, formulation development, or R&D testing, the A1081 offers a dependable and efficient solution for lubricant foam analysis.

Working Principle
The A1081 Lubricating Oil Foam Characteristics Tester works by injecting clean air through a diffuser into a lubricating oil sample maintained at a specified temperature. Under standardized airflow conditions, foam is generated within the sample cylinder.
The instrument then evaluates two critical parameters:
- Foaming Tendency – the volume of foam immediately after air injection
- Foam Stability – the remaining foam volume after a defined settling period
Testing is usually performed in multiple temperature stages to simulate real operating conditions encountered in industrial systems. This helps determine whether the lubricant can resist foam formation and rapidly release entrained air during operation.
The A1081 provides highly repeatable results, allowing laboratories to compare lubricant formulations and verify compliance with product specifications.
