• CFR-A1 AUTO Gasoline Octane Rating Unit This instrument is applied to determine the octane number of motor gasoline and gasoline for spark-ignition aero-engines, including the Motor Method (MON) and Research Method (RON). Its test range is 40～120 O.N. It can automatically and accurately locate the maximum knock liquid level without manual operation. The test can be performed fully automatically with one click, featuring high accuracy and efficiency. It provides users with a brand-new operating experience and delivers precise and reliable measurement results.

Applicable Standards: GB/T 5487, ASTM D2699, IP 237, EN ISO 5164 GB/T 503, ASTM D2700, IP 236, EN ISO 5163
