RapidOxy 100 Fuel – the only RSSOT on the market – investigates the fuel oxidation and performs stability tests on spark ignition fuels, diesel fuels ranging from pure diesel (B0) and diesel/FAME (fatty acid methyl esters) blends (B–B99) to pure biodiesel (B100), and also heating oils. This oxidation stability tester fulfills standard methods ASTM D7525, ASTM D7545, and EN 16091 for fuel analysis. Only 5 mL of sample is required, making it ideal for testing costly antioxidants.
