Frequently Asked Questions about the DEF Refractometer

1.What is a DEF Refractometer?

A DEF refractometer is an instrument used to measure the concentration of diesel exhaust fluid (DEF). It works by measuring the index of refraction, which is a value that indicates how quickly light passes through a liquid—in this case, the DEF.

This measurement is then used to calculate urea concentration in the DEF, which is necessary for diesel engines. A lens wipe cloth is also used with a urea concentration refractometer.

2.How Does a DEF Refractometer Work?

The DEF Refractometer measures DEF concentration using a beam of light that passes through the sample. This beam is then broken up into two beams traveling in different directions, with one of these beams hitting a sensor located on the refractometer. The sensor then calculates the refractive index, which is used to determine the concentration of DEF.

3.When Did They Install an SRC System on Diesels?

Diesel engines manufactured in 2010 began installing SCR systems on heavy-duty diesel engines. Other manufacturers, such as Cummins and John Deere, followed suit shortly after. Selective catalytic reduction systems are designed to lower NOX gasses and conform to EPA regulations for lowered NOx emissions standards using a urea solution.

4.What Is Needed for Proper System Operation?

Many components must be combined to ensure your vehicle consists of the proper operation of a selective catalytic reduction system. This includes DEF pumps sepparate from the diesel fuel pumps, bulk DEF dispensers, and other parts. Many large truck manufacturers have installed bulk def dispensers to utilize SCR emissions control, which includes Detroit diesel engines.

Final Thoughts About DEF Refractometer

For those looking for a reliable tool to measure the quality of DEF in their tanks accurately, the DEF Refractometer is an ideal choice. Its ability to consistently provide accurate readings on urea concentrations can help ensure that your SCR system is appropriately operating as it should.

And with its lightweight and portable design, you can take it anywhere! So, whether you are a professional mechanic or an avid diesel enthusiast, the DEF Refractometer is worth investing in.
