New EPA regulations require all diesel engines manufactured on or after January 1, 2010, to meet lowered nitrogen oxides (NOx) standards. In order to meet these requirements most diesel engine manufacturers have chosen to utilize Selective Catalytic Reduction (SCR) technology. SCR-equipped engines require a solution known as Diesel Exhaust Fluid (DEF), a urea solution, to enable this process.  

"To ensure proper operation of the SCR system, vehicle operators and technicians must make certain that the DEF used in their vehicle consists of the correct 32.5% concentration of urea and water," says Eric Adamson, OTC product manager of equipment and heavy-duty tools, SPX Service Solutions. "Enter the new 5025 DEF Refractometer from OTC, an SPX brand, a device that provides a fast and convenient method for evaluating the DEF condition in a matter of minutes." 

The 5025 refractometer is a portable, precision, optical instrument used for measuring the DEF concentration. When a liquid sample is placed on the prism, the light passing through it is bent. The more concentrated the liquid, the more the light will bend. It contains a reticle, or scale, that is enlarged through the eyepiece to measure this light; and the values on the scale have been established to evaluate the DEF condition. According to Adamson, simply place a small liquid DEF sample on the refractometer prism, look through the eyepiece, and read the scale, which has been specifically calibrated for DEF.

The OTC 5025 kit includes the Refractometer, a dropper, the lens wipe cloth, instructions and a quick reference guide. It also includes a screwdriver and a durable case.   

Additionally, SPX has added two new upgrade kits for the OTC DPF Cleaner (P/N 5280). These new upgrade kits include coverage for Detroit Diesel (P/N 556889) and Navistar (P/N 558181) engines.
