UREA REFRACTOMETER

• EPA regulations require all diesel engines manufactured on or after January 1, 2010 to meet lowered NOx emissions standards. • These new 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 system, operators must ensure the DEF in their vehicle consists of a 32.5% Urea / Water solution. • Scale: 5% line graduations, 32.5% Indicated Scale, 15-40% total scale. • Kit includes: Refractometer, dropper, lens wipe cloth, screwdriver (for calibration) and case
