Octane Number and Cetane Number Tester LOCT-A10 is benchtop unit designed to measure Motor octane number (MON) of aviation gasoline, light gasoline; Research octane number (RON) of gasoline for motor vehicles, blended gasoline, isomerised gasoline, arene gasoline, ethanol and Cetane number of automobile diesel fuel. Test results meets the standards of ASTM D2699-86 and ASTM D613 - 18a. Features like digital transmission technology, anti-jamming, accurate results after several repetitions, less sample volume, short test time, LCD display etc. makes it highly reliable. It is widely used in testing labs, petroleum industry, quality control, etc.
