GUM CONTENT TESTER AZA1317

The AZA1317 Gum Content Tester from AZA Lab is a precision laboratory instrument designed to determine the existent gum content in aviation gasoline and motor gasoline. Existent gum testing is critical for evaluating fuel cleanliness, storage stability, and combustion performance, helping prevent injector fouling, valve deposits, and engine performance degradation.

Note: This instrument is not suitable for aviation turbine fuel testing.

With accurate temperature control, efficient evaporation, and multi-sample capability, the AZA1317 is ideal for fuel testing laboratories, refineries, inspection agencies, and quality control departments.

Description

Description

Operating Principle

The AZA1317 determines existent gum by evaporating a measured volume of gasoline under controlled temperature and airflow conditions. After evaporation, the residue (gum) remaining in the test vessel is measured, providing a direct indication of fuel cleanliness and oxidation stability.
