$21.99 Refractometer for Battery, Anti-freeze, and DEF
Check out this $21.99 refractometer on Amazon. Lotta bang for the buck. Received it yesterday. Seems reasonably well-made and appears to work as advertised.

OK, 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 . . .

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.
