DIESEL FUEL HYDROMETER

• Quickly troubleshoot engine performance problems and measure #1 and #2 grade diesel fuel quality. • The hydrometer measurements are given as an American Petroleum Institute (API) gravity reading when testing diesel fuel composition and combustion characteristics. • Fuel is drawn into the hydrometer tube which then floats the internal bulb float. The internal float contains a thermometer that is used to compensate the API reading for the highest accuracy. Instructions included. • Hydrometer Scale: 30 to 110. • Correction Scale: +2.5 to -5.0. • Applications include #1 and #2 grade diesel fuels
