| SR-524C Ramsbottom petroleum products carbon residue tester complies to SH/T0160, ISO4262, ASTM D524 and is mainly used to test the non-volatile petroleum products that are partially decomposed during atmospheric distillation. When using the instrument, put an appropriate amount of sample into a special glass coking bottle with a capillary tube, and place it in a metal furnace maintained at a certain temperature. The sample is quickly heated to a temperature at which all volatile substances escape from the bottle mouth, while the heavier residues remain in the bottle for cracking and coking reactions. |
