    This instrument is designed and manufactured according to the experimental method requirements of the industry standard SY/T7509 "Determination of Residue of Liquefied Petroleum Gas" in the People's Republic of China. It is suitable for determining the content of residue after the volatilization of liquefied petroleum gas at 37.8 ℃. It is to evaporate 100mL of liquefied petroleum gas sample in a centrifuge tube, measure and record the residual volume left at 37.8 ℃. Simultaneously record the phenomenon of adding a certain amount of solvent and residue mixture droplets onto filter paper.
