• Digital DEF Refractometer Overview

    The Diesel Laptops Digital DEF Refractometer is the ideal tool for testing Diesel Exhaust Fluid (DEF) quality. Diesel Exhaust Fluid is used in every commercial truck since 2010, and all off highway diesel engines had to meet Tier IV guidelines in 2014. This means there are literally millions of diesel engines in use every day that require DEF to operate properly.

    Having poor quality Diesel Exhaust Fluid (DEF) can ruin your DEF Pump Module, DEF Doser and even your SCR Catalyst. To avoid these costly repairs, DEF quality must be checked often and there is no easier way to check your DEF quality than with the Diesel Laptops Digital DEF Refractometer. 
    Using this tool is simple. Place a few drops of DEF in the stainless steel testing area, press the button, and you will have your results in seconds on an easy to read display. You can easily take multiple readings to ensure you have the most accurate results possible.

    Digital DEF Refractometer Features

    Digital Readout

    Remove the possibility of human error when reading sight glass measurements from non-digital models. Sight glass Refractometer readings can also be greatly effected by poor lighting condition and technician viewing angles. These problems go away with a digital model.

    Automatic Temperature Compensation

    With traditional, manual DEF Refractometers the temperature of the surrounding air can influence the readings, and if not taken into account will give inaccurate results. This digital Refractometer includes a sensor to read ambient air temperature and calibrates itself accordingly.
