Abstract
A portable diesel fuel tester and a method of its use are provided. A sample of diesel fuel is placed in a sample tray of the tester. The diesel fuel is heated to a gas state and circulated to a SO2 sensor by an air pump. The SO2 sensor determines the level of sulfur in the diesel fuel based on the SO2 levels. The sulfur level is displayed on an LCD screen for viewing by the user.
