Its clear prism and eyepiece-augmented reticle translate liquid density into a readable value, turning a simple sample into actionable data you can trust for routine SCR maintenance.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003ePlace a liquid sample on the prism; light bends more as the liquid becomes more concentrated. The enlarged reticle presents a DEF reading on a scale that technicians use to evaluate the solution. Key details include a 0.5 percentage step, a 32.5% reference line, and an indicated range from 15% to 40%, with a waterline reference at 20°C.\u003c\/p\u003e\n\u003ch3\u003eWhat’s included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRefractometer\u003c\/li\u003e\n\u003cli\u003eDropper\u003c\/li\u003e\n\u003cli\u003eLens wipe cloth\u003c\/li\u003e\n\u003cli\u003eInstructions and Quick Start Guide\u003c\/li\u003e\n\u003cli\u003eScrewdriver\u003c\/li\u003e\n\u003cli\u003eCase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy it matters for your fleet\u003c\/h3\u003e\n\u003cp\u003eSCR-equipped engines rely on properly mixed DEF to support lower NOx emissions.
