Pocket >> Palm >> Perform IoT Supported With NFC Technology
The PAL-Urea is specifically designed to measure the Urea concentration of Diesel Exhaust Fluid (DEF), also known as AdBlue* in Europe. Already proven in Europe as the only reliable, go-to instrument for easy and accurate checks, the PAL-Urea is now available in North America in time for new 2010 EPA regulations on diesel emissions.DEF needs to have a 32.5% Urea concentration in order to work effectively in SCR engines. Make sure that the DEF that comes out of your pump and into your tank is pure in quality and safe from potentially harmful additives by using the only digital hand-held refractometer already trusted by European consumers.* AdBlue is a trademark of VDA.

Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two –NH2 groups joined by a carbonyl (C=O) functional group.
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colourless, odourless solid, highly soluble in water, and practically non-toxic (LD50 is 15 g/kg for rats).[5] Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. The liver forms it by combining two ammonia molecules (NH3) with a carbon dioxide (CO2) molecule in the urea cycle. Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry.
Applications include
- Urea Concentration, Diesel Exhaust Fluid , DEF, AdBlue
AdBlue® is an aqueous solution with a concentration of 32.5 % urea. In North America, it is referred to as DEF (for "diesel exhaust fluid"). Urea reacts with nitrogen oxides and creates environmentally safe nitrogen and water. AdBlue® is therefore added to diesel to lower nitrogen oxide emissions. In countries where taxes are graduated according to vehicle emissions, reduced emissions of nitrous oxides may be cost efficient. Moreover, the addition of AdBlue® results in a reduction of fuel consumption by 3 % to 8 %.
