The refractometer is a portable precision optical instrument used for measuring the diesel exhaust fluid concentration.
AIRCRAFT ALUMIUM BODY MATERIAL:The Urea Concentration Refractometer is made of non-staining, non-corrosive and non-reactive aluminum which is lightweight to carry,anti-scratch and durable.
EASY TO USE:Just need 2-3 drops of solution, you can get accurate readings. No batteries needed.
Equipped with “Automatic Temperature Compensation” (ATC) for accurate measurements without recalibration after shifts in ambient working temperature (field use).The "ATC" range is 10'C-30'C (50'F-86'F).
3 DROPPERS BONUS:In consideration of some customers feedback say 1 dropper is not enough for frequent uses,we have packed 3 droppers for you.Every piece of our products is strictly inspected before sale.If this product fails through faulty materials or workmanship, contact our service department direct on amazon.
What is Diesel Exhaust Fluid (DEF)? 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!
