Atago PAL-Urea Diesel Exhaust Refractometer (0-55 Urea)

PAL-Urea2-sA refractometer is widely used in the food production industry and is becoming increasingly popular in the beer making process as it provides a quick and easy way to determine the specific gravity before and after the fermentation process. They are useful in maple syrup, honey and sugar production for the quick brix, or sugar content, reading.

Another use is for measurement of industrial cutting oils and liquids. Refractometers have evolved from a simple analog prism to a highly accurate electronic device capable of wide scales of the refractive index, brix or specific gravity. Conversion of one measurement scale to another is a simple calculation of a conversion factor.

This instrument is specifically designed to measure the Urea concentration of Diesel Exhaust Fluid (DEF), also known as AdBlue in Europe. As the number of selective catalytic reduction (SCR) engines on the road increase so does the demand for accurate testing of the DEF.

Diesel Exhaust Fluid needs to have a 32.5% Urea concentration in order to work effectively in SCR engines. This meter can make sure that the DEF that comes out of the pump and into the tank is pure in quality and safe from potentially harmful additives by using the only digital hand-held refractometer already trusted by European customers.

This meter features no moving parts and is designed to be rugged and long lasting. To test simply place a few drops of DEF on the prism, press the start button and the PAL refractometer displays the reading in only 3 seconds. This meter is also equipped with automatic temperature compensation allowing for accurate readings within a larger range of temperature.
