Diesel Exhaust Fluid is a solution made up of purified water and 32.5 percent automotive-grade urea
that is used as a carrying agent for the ammonia needed to reduce nitrogen oxide (NOx)
emissions from vehicles into nitrogen, water and carbon dioxide (CO2). Diesel Exhaust Fluid is
monitored for quality and certified by the American Petroleum Institute, ensuring that Diesel
Exhaust Fluid is a stable, non-toxic, odorless and completely safe solution. The urea used for
Diesel Exhaust Fluid is automotive-grade. Urea in additional forms is widely distributed for
many other industrial and agricultural needs, including emissions control at public utilities and power plants.
Most heavy duty engine (Class 7-8 trucks) manufacturers, have chosen to utilize Selective Catalytic Reduction (SCR).
This Includes Detroit Diesel (DD13, DD15, and DD16 models), Cummins (ISX line), PACCAR, and Volvo/Mack.
EPA regulations require all diesel engines manufactured on or after January 1, 2010 to meet lowered NOx emissions standards.
HOW DOES THE AD-7 HELP ME?
The DEF Refractometer will help determine if it is time to change out your Diesel Exhaust Fluid! Old
DEF is less efftective at treating NOx, therefore a maintained DEF fluid will help reduce NOx
and any potential tickets you may get from a cop! Did you know that research suggests that a
truck running a DEF system can get better mileage! True! Calibrate with Water
(water = 0% Urea Concentration) and wipe clean with a cotton towel, and you're ready to go!

The unit was easy to calibrate and measured the specific gravity of the DEF that I wanted to check perfectly.

I found I had gotten tired of running back to the shop to get the shop's refractometer just to verify the DEF quality sensor took a dump. Purchased this and speeds up diagnostics drastically. Quick sample and look through the glass. Done.As far as accuracy. After is all said and done, the refractometer typically shows 1-2% off of the quality sensor reading on the laptop. Plenty close enough as typically the faulty sensors I run into are off by 10% and out of range

I had to make a minor correction to calibrate mine, but it was easy (tool included). Simple to use; great price; saves you from a derate and a lot of lost revenue and repair costs. You honestly can't afford NOT to have one. Sprinkle a few drops from the DEF dispenser at the pump, go back in your truck for 30 seconds to get the DEF to ambient temperature, and look at the reading. If it's bad, don't buy DEF there.

This refractometer worked great. Very easy to read. I bought it to test the DEF in my motorhome. The only problem I had was getting some of the DEF out of the container in the motorhome. The small siphon tubes they give you are only about 6 inches long so I had to use a long tube to get some out. Once I did that, checking the DEF took about 2 minute. Nice plastic case with padding inside to keep the device safe.
