In line with American Society for Testing Materials Standards: ASTM D 2700 (Motor Method) and ASTM D 2699 (Research Method) In line with the national "Determination of Gasoline Octane Number": GB/T 503-2016 (Motor Method) and GB/T 5487-2015 (Research Method) Used for determining the octane number of vehicle gasoline and ignition aviation engine gasoline. The instrument host uses a CRF standard single-cylinder four-stroke motor with the continuous variable compression ratio, with an industrial control computer, a Windows operating system, high-precision measurement and control components and other many peripheral devices to accurately and effectively perform testing. The tester has many auxiliary functions such as auto display, saving and printing of test report.
