DEF-Chek Digital Pocket Automotive Refractometer 13940013

$ 297.00

Meets ASTM D7821-12 Standard test method for field determination of urea concentration in Diesel Exhaust Fluid (DEF).

With the simple push of a button, the DEF-Chek, the world's smallest handheld digital pocket automotive refractometer, 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 adapted by the major manufacturers to address the requirement. 
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 DEF-Chek 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 in correct concentration will result in potential costly damage to the SCR system (injectors) and failing the emissions standards set by government agencies. 

The DEF-Chek Digital Pocket Automotive Refractometer operates on 2 x "AAA" batteries, included. The DEF-Chek has an automatic shutdown mode, so the battery life is extended to 10,000+ measurements. DEF-Chek is IP65 rated for water resistance and is dust proof. It is supplied with a detachable neck lanyard and ergonomic rubber side grips for ease of handling.
