SmartRef Digital Refractometer by Anton Paar – Coffee TDS Refractometer with in-App Extraction Yield Calculator, Smart, Easy, Quick, Digital, Coffee Tester

Excellent product.

I wanted to check the alcohol content of Kefir to make sure that there was none. I used this in conjunction with the EasyDens and their app. Easy to use and very reassuring.

Great product. Performed as advertised. Measurement compared to manual process and matched.

I have used for two home brews and worked very accurateMust have if serious about your beer quality. I wished I would have had this device sooner. Yes, I highly recommend at this price point.

I bought the combo of the SmartRef and EasyDens and for some reason the SmartRef was already opened on the inside with the guides outside the packaging and one of the plastic liquid droppers having been used

I've been using this with the EasyDens to get ABV readings for the beer I brew. The readings obtained are spot on with known samples.

So easy to connect to the app and use it. I have been brewing my kombucha for a bit now and I wanted to check the sugar content to see how well fermented it is. It took a second to show me the Bx. That means 6.6 grams of dissolved solids in 100ml water. It won't tell you exactly how much of that is sugar. But it gives you a good idea. I think with time and more trials, I should be able to come up with the perfect number to determine if it's ready yet. I know your taste buds are the best thing when it comes to determining that, but I like having solid numbers to go by. This device works great. There are 4 or 5 different apps for different devices they have available. Just make sure to get the right one. The instruction manual doesn't tell you which one, but it's pretty self explanatory.

I purchased this to work in pairing with EasyDens Hydrometer to do acholic levels without having the starting gravity, but I'm question on how Accuracy it is. The same sample of beer on both units and I get different reading even after calibrating. The Digital Refractometer seems to be off. I would love to see more videos on how to clean and use the EasyDens Digital Refractometer and EasyDens Hydrometer . Also love your app but does seem a little expense to pay 24 dollars more after spending 800 on both units. You should offer at least 1 or 2 free.
