This refractometer is for measuring the sugar content of beer and includes an automatic temperature compensation of 10 - 30 degree Celsius. This refractometer can replace your hydrometer for easier and more accurate measurements. Simply use the dropper to take a sample of wort and put it on the prism. Then hold the refractometer up to the light and look through the eyepiece. Due to the dual scale there is no need convert to specific gravity as the scale measures both Brix and SG. Comes in a hard carry case with a 1 year warranty. Please check out other refractometers available from Agriculture Solutions LLC, custom ranges available on request.

Also, the picture is inaccurate. This does not come with a hardcase. Comes with the soft case only.
Giving it two stars because it does measure the Brix. But the first thing listed in the advertisement is for "beer wort", and the dual scale is not calibrated for that. There are other refracts out there specifically calibrated for unfermented beer/wort.
This particular refractometer is junk, plain and simple. I calibrated it properly as instructed, each time I used it, but the readings for unfermented wort are just way off. I'm talking both brix and S.G. I confirmed this with my trusty hydrometer (YES, I've already ruled out any issues with my hydrometer)
I partly blame myself for going after the cheapest cost unit on Amazon, but this needs to be fixed immediately before others suffer. Amazon, do what's right and look into this issue.
What no one told me, and I wish they had, is that this device starts to be come very inaccurate once there is alcohol in the solution. So while it's great for measuring the original gravity of your wort, it is not useful once the fermentation process begins. In order to use it beyond the initial boil, you need to gather readings with both a hydrometer AND the refractometer. Then you can calculate an adjustment factor that will allow you to use the refractometer from that point on. I'm told that the exact adjustment factor varies with the specific refractometer, so you need to calculate your own. If I gave you mine here, yours could be very different.
So if you buy this device and you don't have a hydrometer and test jar, do yourself a favor and order those too. Then do an Internet search for relevant brewing articles to see how to calculate and use an adjustment specific to your device.
That may sound like a lot of extra hassle. If you don't mind tossing out those hydrometer samples (or you are OK drinking the flat beer) then you don't need this device. If, like me, you like the convenience of an easy-to-read device and the benefit of being able to get gravity readings with very small samples, get yourself a hydrometer, test jar, and this device. Work out your adjustment factor, and you can put away the hydrometer from that point on... and only need very small samples.
When you look at the photos I've posted, bear in mind that the photo of the gauge was taken by holding a cell phone camera up to the opening and trying to get the device, camera, and light source all in alignment (which is a LOT harder than it sounds). But the beer in question reads roughly 1.075 on the SG scale and 19 on Brix. All I needed to get that reading was a tiny drop of wort from the tap on my fermenting bucket.
I'm also showing photos of extracting the tiny wort sample, using a pipette (included with the device) to get a couple of drops, the drops of liquid on the prism, and the case it came in.
- Great alternative to Hydrometer for monitoring fermentation
- Comes with a hard carrying case, cleaning cloth, and instructions
- Not as accurate/easy to read as a hydrometer
NOTE!!! Refractometers can only be used to measure Original Gravity! After fermentation begins alcohol in the beer will throw off the ability for refractometers to measure accurately. You must still use a hydrometer for post fermentation gravity readings.
