13940013, Digital DEF-Chek
With the simple push of a button, the Reichert Digital DEF-Chek®, the world's smallest handheld digital tester, will quickly and accurately measure the % concentration of Urea in deionized water, commonly referred to as Diesel Exhaust Fluid. Diesel powered vehicles are required to meet new strict EPA, European Commission, and MLIT standards regarding tailpipe emissions. The technology of Selective Catalytic Reduction (SCR) has been adopted by the major manufacturers to address this requirement. In the European market, this SCR technology using AdBlue™ (Diesel Exhaust Fluid) has been accepted and utilized for many years. Diesel Exhaust Fluid (DEF) is injected into the exhaust gasses as a mist before it passes through the catalyst. The catalyst and DEF converts harmful and polluting Nitrogen Oxide (NOx) into harmless nitrogen and water vapor. For this technology to work, the Urea in the deionized water must have an exacting concentration of 32.5%. Any deviation from this Urea concentration will adversely affect this technology. With the growth of SCR equipped diesel engines, automobile and truck dealerships, service centers, trucking fleets, service stations, and truck stops are using Diesel Exhaust Fluid, and it is important to insure the quality of the DEF is maintained throughout the supply chain.
The Reichert Digital DEF-Chek® tester detects changes in the concentration which would be cause 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.
The Reichert Digital DEF-Chek® tester operates on 2xAAA batteries that are included. The tester has an automatic shutdown mode, so the battery life is extended to 10,000+ measurements. The tester is IP65 rated forwater resistance and is dust proof. It is supplied with a detachable necklanyard and ergonomic rubber side grips for ease of handling.
