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
