Aichose Brix Refractometer with Automatic Temperature Compensation for Accurate Measurements

Peter Dohm: There’s nothing to dislike about these refractometers. I’ve used them for years, and compared to the hassle of a bulb, these are so trivially easy to use, and as accurate as they need to be for everything that I’m doing!

Stephen D. Wall: Tests to be extremely accurate. Cheap, easy to use. Repeatable.

Amazon Customer: This refractometer feels good in the hand, is easy to use, has no batteries and provides accurate, consistent results.

However, you have to understand that if you are using to check the brix/specific gravity of a fermentation, the result will differ from a floating hydrometer. This is due to the additional effect of alcohol in the wort, which affects refraction more than the floating hydrometer.

For example, my nearly fully fermented mead SG measured 1.050 on this refractometer, but indicated 1.010 on my floating hydrometer. I rechecked with 2 other refractometers and the results were consistent. The apparent inaccuracy was not the result of a faulty refractometer.

S. Garcia: This refractometer does exactly what it is supposed to do. Measure Sugar content. I use it to brew beer. Works well. BUT! For final gravity you need to use an conversion tool. Refractometers are off when reading final gravity because of the ALCOHOL. Tools are on-line. Using an conversion tool will give you proper final gravity.

Ranger B: 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...
