13940013 DEF-Chek Digital Pocket Refractometer
Selective Catalytic Reduction (SCR) systems for diesel automobiles, trucks, buses, and off road equipment require pure Diesel Exhaust Fluid at an exact concentration of 32.5% urea in deionized water. This fluid is known as DEF, AdBlue, ARLA, and AUS 32. Any other concentration compromises the SCR system, which fails the regulatory requirements of governmental agencies such as the EPA, European Commission and MLIT.
The Def-Chek digital instrument accurately measures DEF for the right urea content detecting whether the fluid will do its job in the exhaust system. The world's smallest scientific DEF testing device offers quick, automatic digital measurements in seconds and provides over 10,000+ measurements on two "AAA" batteries.
The Def-Chek tester detects changes in the concentration which would be caused by water dilution and adulteration. Check the concentration of Diesel Exhaust Fluid (DEF) like you would check the concentration of engine coolant (Antifreeze). Both DEF and engine coolant have been chemically formulated to work effectively at a specific concentration. An incorrect concentration will result in potential costly damage to the SCR system (injectors) and failing the emissions standards set by government agencies.
