Awarded one of MOTOR Magazine’s TOP 20 NEW TOOLS for 2011! The Reichert Digital DEF-Chek®... the fast, accurate, state-of-the-art digital instrument for testing Diesel Exhaust Fluid (DEF) Clean exhaust systems for cleaner air. Maintain optimal SCR performance and keep rolling at 32.5% concentration, 100% of the time 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. Reichert DEF-Chek®: digital, state-of-the-art protection for your SCR system. The Reichert 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 Reichert DEF-Chek® was chosen by MOTOR magazine as a MOTOR Top 20 Tools Award.
