- TrackrigExplorer IIOK, now that you have it, what are you going to do with it? I had enough curiosity to spend 45 seconds researching and still don't know what it does. This sounds like something Supercharged would have posted.......
Refractometer
Choose one, measure everything
Measure the refractive index and concentration of liquids, gels and solids using laboratory refractometers from Anton Paar – the universally applicable and user-friendly Abbemat series. Simply take your pick depending on the accuracy, temperature range and level of automation you require - you can be sure to find a digital refractometer model to suit your application and budget.
There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases. In veterinary medicine, a refractometer is used to measure the total plasma protein in a blood samples. In drug diagnostics, a refractometer is used to measure the specific gravity of human urine.

1) Measure a battery's state of charge. Readings are more accurate than a voltmeter, plus you can check individual cells.
2) Calculate the freezing point of your anti-freeze---make sure your antifreeze is mixed properly.
3) Diesel owners can check DEF before using it to make sure it has the correct concentration of urea (32.5 percent). Folks have had to pay big $$ to have their DEF tanks drained, flushed, and filled after using bad DEF.
For some folks it offers a lot of functionality for $21.99; for others, maybe not. - TrackrigExplorer IIAnd now I've been educated on something once again.
Bill - pigman1ExplorerFirst class. I have one that measures battery specific gravity and antifreeze freeze point but the DEF feature is a worthwhile addition. Thanks.

If your refractometer can measure a battery's specific gravity (and the freeze point of antifreeze), I'm guessing it should be able to measure DEF, too. The refractometer only measures the concentration percentage of soluble solids dissolved in the water. The concentration percentage of usable urea is within the concentration percentage range of battery acid's specific gravity.
First class. I have one that measures battery specific gravity and antifreeze freeze point but the DEF feature is a worthwhile addition. Thanks.
According to my refractometer (with a urea scale), a sample of DEF will read approx. 1.31 on the battery specific gravity scale if the urea concentration is 32.5 percent (ideal). Approx. 1.33 if the urea is high at 34 percent, and approx. 1.29 if the urea is low at 31 percent. I believe the urea concentration percentage tolerance for Cummins is +/- 1.5 percent or 31 - 34 percent. - The_real_wild1ExplorerMakes sure you clean it with water after using it. Especially with def. Also make sure it is calibrated. I have never used a cheap one like that so I'm not sure how accurate it will be. There should be calibrating instructions that came in the box.
- SCVJeffExplorerMine measures the salinity in my reef tank and is more accurate than my floater. They're very handy for allot of things
- Kafn8tdExploreryou can also use it to brix your juice concentrate.

Exactly. DEF will leave crystalline deposits so flushing with water is a must after measuring a sample.
Get DISTILLED water from a store. You can usually get it for 99 cents/gallon. Do not use Deionized (DI) water because it is highly polarized from the ion exchange process and can attack some metals. Distilled water has been boiled to remove salts and metal ions and the steam condensed over chilled coils. It is a much better water to use for flushing devices like this refractometer, topping off batteries, or diluting full strength engine coolant.
