Alcohol Refractometer

For a maple syrup hobbiest like me, this really made the process much more precise, and I ended up with good results.

All good

Works perfectly fine, but feels cheap in your hand. Which, of course it does, because it's cheap.

The wide range tells me how much more boiling my maple sap needs before it is done. The narrow range units are more precise but are useless until you are almost finished. Much more informative than trying to use the temperature.

First, this is not a beer/juice refractometer - that's a different refractometer. This is for spirits. Here's how to use this correctly: first, adjust the eye focus so you can read the numbers sharply. Then use the dropper to take some of your spirit, place it flat on the window and make sure you get the window pretty wet! You want it flat so it doesn't slide off. Then close the flap and the liquid underneath should be an obvious dark blob. If it isn't, add some more! Now hold it up towards a bright light (sun works great) and you should see an obvious sharp line between the dark top and bottom white and that's your alcohol %. If it's blurry, then press down a bit on the flap, make sure you're looking directly at a bright energy source, and then maybe adjust the focus. Then make sure you wipe both the window and flap after each use, and make sure you give the dropper a good cleaning with soap and water or acetone after every day you use it. Otherwise you will get nasty mold growing in the dropper. And that's not the fault of this product, it's just because you left something sugary in it. This is vital when you're distilling - you want to check every single jar ('cut') and check the ABV. You'll generally see 80% to start with, then dropping slowly (or in jerks) down to 40%, and once it gets well below 40% you're done. Also vital when you're blending, because then you can check the 'finished' blend and decide whether you need or want to dilute it with some water to get to about 45-50%. And you can't tell without this. Some people say they can, but a very smooth 65% is a lot more mellow than a harsh 45% and I've seen them guess spectacularly wrong. So just get this and you can use it forever.

Cumple su función y lo uso para mi pecera todos los días

I took a chance, I had never used none of these before. I feel pretty good about this one

Seems to work OK but you can tell it's put together cheaper than others. Does the job though

Es muy difícil de enfocar el resultado pero después de buscar el ángulo se puede observar parcialmente. Muy económico y fácil de calibrar

Buena precisión una herramienta que no puede faltar en tu consultorio
