OTC's 6750 Diesel Fuel Hydrometer allows technicians to quickly troubleshoot engine performance problems and measure #1 and #2 grade diesel fuel quality
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; Internal float contains a thermometer that is used to compensate the API reading for the highest accuracy
Hydrometer Scale: 30 to 110; Correction Scale: +2.5 to -5.0; applications include #1 and #2 grade diesel fuels
Similar to OE tool number J-38641-D; Instructions included
