MISCO’s Palm Abbe DEF-201 handheld digital refractometer is designed specifically for testing the concentration of urea-based Diesel Exhaust Fluid (DEF). In addition to reading DEF, the refractometer can be programmed to read up to four more critical automotive parameters such as engine coolant freezing-point, engine coolant concentration, brake fluid water content and windshield washer fluid. Options for the instrument include a rubber-armor jacket (in one of three colors), a virtually indestructible storage case and NIST traceable certified calibrations.
