Brix+Specific Gravity

This is exactly what I was looking for as a home beer brewer. The meter is solid and well-constructed. The case is nice, and the dropper to add the sample is perfect. I love the fact that you can adjust the focus on the eyepiece. I wear glasses, and this allows me to take my glasses off and focus the view so that I can see the very easy-to-read scale perfectly. The second scale is in S.G. for wort, which is what I need. No need to do any conversions from the Brix scale. The refractometer came perfectly calibrated. I checked it with distilled water, and it was right on the money. I have not used it on wort for an original gravity (OG) or for the final "measured" final gravity (FGm), which will need to be calculated into the true final gravity (FGt) to get my Alcohol by Volume (ABV) for my brew. But I have no doubt that this will work since it was perfectly dialed in when I received it. Even if the OG is not exactly what I would get with a float hygrometer (I have no reason to doubt that it would not be), as long as I use it for both my readings, and apply the 11-gravity point correction for alcohol the ABV will be accurate because if it is off on the first reading, it will be off the same amount on the second reading, canceling out the error. And, let's face it, ABV is what I really care about. I have also found that if I feed the OG reading and the FGm reading into my I.A. (Gemini), and ask it to give me the ABV from my readings, it will make the corrections to come up with the FGt from the FGm and give me the ABV. I don't even have to go hunt down a wort calculator. Just a heads up, though, the "Alcohol Gravity Point Correction" on my refractometer and, therefore, I would imagine on all in this product line, was 11 Points. The usual is between 5-7 points. I discovered this by testing a known commercial beer. Knowing the actual FGt of that beer and comparing it to my FGm, I was able to determine the actual 11-point correction. So, to figure out your FGt make sure you plug into the calculator or let your chosen AI know that it is an 11 gravity point correction for alcohol for this refractometer from your FGm (or check yours yourself). I still love this thing.

Yeah, I bought this to use on my moringa plants to find out what my sugar levels were and my bricks are between 20 and 25 bricks on my moringa trees which I guess is pretty high. I really recommend this. It works great and it’s very useful and the quality is very good. RCH.

Works as should. Easy to use!

I received the refractometer and was generally impressed. Nice case. Included good instructions, a small screwdriver for adjustment, cleaning cloth and two dropper/pipettes. The unit, when tested with plain water, read dead zero. I then compared to some muscadine wine I am fermenting and had conflicting readings with my old glass hydrometer. I suppose the old adage of a man with two watches never knows what time it is! is true. I cannot explain the difference. However, the truth is, in beer and wine fermenting, that what I am looking for is stoppage of the reduction in S.G. This indicates that the yeast has done all it can, that the fermentation has slowed to a crawl, and it is time to rack (wine) or bottle (beer). Don't assume anything from this review since I have only had it for two days. But I will say this: Repeated readings were exactly the same each time. It certainly requires only a tiny amount of sample to test each time. Three drops or so. The visual display is super easy to read and very clear, once focused for your eye. I don't see any reason why this cannot be very useful for determining when fermentation is complete. It is nicely packaged. Works well. Perhaps my old, cheap glass hydrometer is at fault regarding the differences in SG readings. Get one yourself and decide.

Since this unit includes an SG Wort scale (specific gravity of wort), do not assume this is a universal specific gravity measurement. The SG is calibrated for wort, but can be used with other liquids if you know the math. Refractormeters work on the principle of measuring refractive index. Since there is a known relationship between the refractive index (ri) and specific gravity (SG) for a particular liquid, the reticle on this model scale is graduated to read Brix for sugar solution and SG for wort only. Some negative reviewers have commented that their aquarium's salt content was way off using this device. They should either use a refractometer with a scale specifically for saline, or do some math while using this unit. This model is made for Brix (sugar solution concentration), and SG Wort (specific gravity of wort). These are the formulas for conversion: SG Wort as function of Brix: SG Wort = (Brix / (258.6-(Brix / 258.2)*227.1)) + 1 Brix as function of refractive index (ri): Brix = 0.0087 + 699.82353*(ri - 1.3330) - 1801.9215*(ri - 1.3330)^2 + 4696.422*(ri - 1.3330)^3 - 6427.26*(ri - 1.3330)^4 For extra credit, you can substitute the 2nd formula into the 1st to find SG Wort as a function of ri. For example, if at a certain temperature the refractive index (ri) of seawater is 1.3394 when its specific gravity is 1.0264, you can calculate the Brix and SG Wort values using the above formulas where ri is set to 1.3394: Brix = 4.4 SG Wort = 1.017 In other words, you need to observe 1.017 in the reticle SG Wort scale to know that a seawater solution has a specific gravity of 1.0264 (and be sure the temperature of the measured sample matches that of the source data). This may explain why some are obtaining readings which do not compare when used for other purposes other than sugar/wort. As far as my experience with the unit, it is sturdy, reliable, and is a great value at this price. Just know what you're getting into.

I tested the calibration with distilled water once received and it was perfect, 0%. I then tested a 20% sugar mix with 40g water and 10 grams of sugar, it tested perfect. My picture isn't super clear, but it is visible.

very good and accurate, lasts a long time too. bought this quite a number of years ago for use at work to check CNC machine coolant concentration. still holding up beautiful! the small rags it comes with are really good for cleaning micrometer faces too!

We bought a Ninja slushie maker and finding the right mix to make a slush was a little hit or miss. Especially, when using sugar-free ingredients. Someone in a group, recommended this and now, it's super easy to make the slushes. It seems very high quality. The instructions tell how to calibrate it. It doesn't take up a ton of room in the drawer. If you make slushes, I would recommend.

Evidencia adecuada relación calidad precio pero no me gusto que no tenga el destornillador para ajustar la óptica
