EPA regulations require all diesel engines manufactured on or after January 1; 2010 to meet lowered NOx emissions standards.� Most heavy duty engine (Class 7-8 trucks) manufacturers; have chosen to utilize SCR. This Includes Detroit Diesel (DD13; DD15; and DD16 models); Cummins (ISX line); PACCAR; and Volvo/Mack.� SCR-equipped engines require the periodic addition of Diesel Exhaust Fluid (DEF; a urea solution) to enable the process. DEF is available in a bottle from most truck stops; and some have installed bulk DEF dispensers near the Diesel Fuel pumps. However; to ensure the proper operation of the SCR system; operators must ensure the DEF in their vehicle consists of a 32.5% Urea / Water solution.� The OTC 5025 makes this a simple and quick process for an operator or technician to get an accurate measurement of UREA concentration in DEF or AdBlue solution.Scale: 0.5% line graduations32.5% IndicatedScale 15-40%Waterline & 20 Deg.
