I. Overview
This Octane number tester complies with the standards prepared by the American Association of Testing and Materials.
ASTM D2700-08 (Motor Method), ASTM D2699-08 (Research Method)
This Octane value tester complies with the latest national standard "Determination of gasoline octane number"
GB/T 503-2016 (Motor Method), GB/T 5487-2015 (Research Method)
This Octane number analyzer is used to measure the octane numbers of automotive gasoline and spark ignition type aircraft engine,with the test range of 40~120.
The Octane value tester body is a standard single-cylinder engine with continuously variable compression ratio, to accurately and efficiently conduct the test through the industrial control computer, Windows operating system, high-precision measurement and control components and abundant external devices, with automatic display, save, test reports print and other auxiliary functions.
