Diesel Exhaust Fluid (DEF) Quality & Testing

Diesel Exhaust Fluid (DEF) is used to reduce NOx gases to nitrogen and water vapour in the presence of a catalyst. As DEF is injected directly into the aftertreatment system, the need for quality control is pivotal to ensuring optimal operation of the equipment in question. Deterioration of DEF quality can have severe consequences on the aftertreatment systems and significantly reduce its lifespan.

DEF quality control can take different shapes such as the use of portable refractometry equipment (see image) , which is used to ensure DEF quality at all stages of production and / or transportation. Refractometry equipment measures the breaking index of the fluid by light, provides DEF quality assurance and calculates the corresponding DEF concentration.

Onboard DEF sensor systems, installed in modern equipment, monitor DEF quality and concentration in the DEF tank. Advanced laboratory equipment is also used to check DEF quality and concentration during production and delivery stages.

DEF testing equipment is in use across North America to ensure the best DEF quality. You can use discoverDEF.com to search for DEF quality equipment providers.
