“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 percent concentration of urea and water,” says Eric Adamson, OTC product manager of equipment and heavy-duty tools for SPX. “Enter the new 5025 DEF Refractometer from OTC, an SPX brand.”
The 5025 refractometer is a portable, precision, optical instrument used for measuring the DEF concentration, the company says. 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. SPX says the refractometer 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.
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 case.
