DEF Refractometer

DEF Refractometer

Introducing the Original DEF Refractometer

Utilize its enhanced prism technology to precisely calculate the quality of the DEF in your truck's tank. It includes a dropper to extract the fluid, a screwdriver to adjust the prism, cleaning cloth, storage case, instruction manual, and the refractometer.

Why Do I Need This Refractometer?

SCR Coolant Leaks

Most SCR systems are designed with a thermostatic control valve that heats the DEF fluid if it reaches freezing point. A leak in this system can contaminate the DEF concentration.

Limited Shelf Life

The shelf life of DEF is approximately one year. Therefore, in scenarios where you are just buying a used truck (which sit idle for long periods of time) that has leftover DEF in the tank, it is vital you check the quality of the fluid before operating the tractor.

Evaporation

DEF tends to turn to vapour, and incorrect urea concentration levels are a direct cause of diesel exhaust fluid evaporation.

What is Refraction?

Refraction is the relative speed of light through a substance versus the speed of light through standard air. There are four fundamental types of refractometers: conventional handheld, advanced handheld, research facility or Abee , and associated method.

Ideal Use For

Diesel Engine Mechanics

Diesel engine mechanics need to be knowledge about the urea/de-ionized water content in their clients’ vehicle when diagnosing problems.

DEF Dispensers

Those that sell diesel exhaust fluid products and operate a dispensary can take advantage of this DEF refractometer.

Owner Operators

Owner operator drivers need this product to perform preventative maintenance on their class 8 trucks.

Medium Duty Truck Owners

Medium duty truck owners who own diesel powered vehicles from brands such as Ford, Chevy, and Dodge will find this tool a highly useful one.

DEF Refractometer Background

Due to the reliance of the refractive index on the wavelength of the light utilized (i.e., scattering), the estimation is ordinarily an estimation at the length of the sodium line D-line (NaD) of ~589 nm. In turn, it is either sifted through from sunlight or created with a monochromatic light-emanating diode (Drove).

Refractive file might estimate both ethylene glycol and propylene glycol. With an end goal to decrease environmental contamination, the European Association has built up specific standards about outflows from overwhelming and light merchandise vehicles. One strategy received by vehicle producers to permit consistency is SCR (Particular Reactant Lessening), which artificially decreases NOx-discharges utilizing a urea added substance in the fumes stream.

Diesel Exhaust Fluid (DEF) is referred to as AdBlue outside the United States. They are put away as a focus in a different tank preceding blending with the fumes gases as they leave the motor.

Keeping in mind the end goal to keep up the effectiveness and to make sure that frameworks are not bargained, it is essential that the fixation is precisely kept up. Estimating gadgets, for example, refractometers and hydrometers may perform such checks and rely upon the area and precision required.

Programmed refractometers consequently measure the refractive list of an example. The programmed estimation of the refractive file of the model depends on the assurance of the primary point of aggregate reflection. An
obstruction channel ensures the predetermined wavelength.

Because of centering light to a spot at the crystal surface, an extensive variety of various points is secured. Contingent upon its refractive record, the approaching light underneath the necessary edge of aggregate reflection is mostly transmitted into the example, while for higher points of the rate the light is completely reflected.

This dependence of the bent light force from the episode edge is estimated with a high-determination sensor exhibit. This strategy for distinguishing the point of aggregate reflection is autonomous on the example characterized.

It is even conceivable to gauge the refractive record of optically thick emphatically retaining tests or tests containing air pockets or active particles.

Furthermore, just a couple of millimeters are required, and the example can convalesce. This a guarantee of the refraction edge being independent of the pulsations and other natural disturbing engagements.

As fixation increases, a refractive list is additionally temperature dependent As temperature increments refractive list diminishes. In instances of refractometers the heat of a critical factor. This is because of the way that for refractive file measurements, only a drop of a test is required; the mass of this sum is small to the point that it will very quickly accept the heat of the instrument.

The temperature of the tool is dependent on the on the temperature of the earth in which it is utilized to. If this temperature is changing decently regularly, such as refuse with autos pulling in and out, the refractometer should be made to a material which will rapidly equilibrate with these changes.

Heavy, metals bodies go about as a warmth sink consequently lighter polycarbonate bodies that react to these temperature shifts is favored. For frameworks to perform proficiently, the def arrangement blended with the fumes gases must be unequivocally 32.5% with a little edge for a mistake.

Even though the minimal effort e-line optical refractometers might be utilized to screen DEF, numerous clients think that its compacted field of view excessively troublesome, making it impossible to work with all the time thus decide on an advanced model.

The Auto A4 DEF/C-EG digital refractometer (code 38-65) invalidates every one of the issues ordinarily connected with the visual estimation by giving a basic “drop-on and squeeze read” estimation arrangement, and also applying a precise temperature adjustment keeping in mind the end goal to additionally decrease potential impurities.

Auto producers that pre-accuse DEF frameworks of liquid may continuously screen the centralization of Def utilizing an RFM-Stream refractometer fitted on a sidestep line. The fixation might be perused from the show or all the more advantageously, of a system associated with the remote show, PLC or potentially information catch gadget, where caution signs might be pre-set for DEF focus at 32-33% urea.
