Brewers love using refractometers for their ability to give quick, accurate readings with a small sample.

The HI 96811 Digital Refractometer is easy to use. Start by calibrating it with deionized or distilled water, then use a small sample from your brew to get a reading within seconds. Readings are displayed in degrees Brix, whch can easily be converted to Specifig Gravity.
  • Temperature: (in C or F) is displayed simultaneously with measurement on the large dual level display along with other helpful message codes.
  • Wide Range: The HI 96811 is versatile enough to fit most applications.
  • Easy Measurement: Place a few drops of the sample in the well and press the READ key.
  • Calibrate with Water: Fill the sample well with distilled or deionized water and press the ZERO key.
  • Automatic temperature Compensation (ATC)
  • Battery Operated: The HI 96811 is operated by a single 9V battery for portability.
  • Dual-level LCD: The dual-level LCD displays the measurement as well as temperature readings simultaneously.
  • Waterproof: The HI 96811 offers IP65 waterproof protection.
  • Quick, Precise Results: Readings are displayed in approximately 1.5 seconds.
  • Small Sample Size: The HI 96811 is able to read samples as small as 2 metric drops.

I have completely shifted over to a Brix view of the world and would like to replace my refractometer with an easier to use instrument.

What is the wort correction factor for this item?
Jeffrey Hewit on Jan 22, 2022
Can this be used post-fermentation?
Stephen Miller on Mar 15, 2023
BEST ANSWER: Yes! But you will need to adjust the reading for the presence of alcohol. Take a look at the spreadsheets and calculators we list above to make this adjustment.

Expensive and unreliable
Do not buy this. The very first time you use it you may think that it is amazingly easy, accurate, and wastes only a little wort. You would be right on two of the points but wrong on the most important point. If you do the reading again, it will be different. Do it a third time and different still. Keep your hydrometer or refractometer and stay far away from this expensive piece of junk.

Must average out 10 readings.
I bought this after having three previous handheld Refractometers get wet and thus rendered useless. I thought that if I spent $180 on a Digital Refractometer, I would be getting quality and thus make my life and brew day easier. Well, that is not a very accurate bit if reasoning. This item is very unreliable and is only getting worse each time I use... I can take a cup sample of wort and swirl it and use an eye dropper to place 4 drops on to the glass. I get readings like15.9,14.1, 13.9, 14.9, 14.8, 15.1... So, I really have no idea what the true brix measurement is. So, what I do it take as many readings it takes to get the same Brix measurement 5 times, then call it good... sometimes it takes 10 tries, sometimes, it takes more... I have even gotten to the point where I just average out the first 10 readings. Would never recommend this to anyone I like.

No more confirmation bias with gravity readings, quick exact repeatable results. Tiny sample requires, easy to clean and calibrate. Use with a steel mesh filter/strainer as hop particles can skew wort OG tradings

I would give it less than 1 star if I could
I have had this for over a year & it has NEVER given a consistent reading. Any sample other than distilled water, at any consistent temp will give a different reading 9 out of 10 times. This POS has never been accurate or consistent. Biggest waste of brewing tech bnb I have ever spent.

Experience with Hanna Digital Refractometer
I've used this instrument on two brew days. I typically batch sparge and like to take readings after each sparge. I also like taking readings during the boil. (Of course I let the sample cool before placing a drop in the sampling wel.) I am extremely happy with it. It certainly beats squinting through the eyepiece of a handheld refractometer, while trying to steady myself so that I can make out a precise Brix reading. With a handheld instrument, there is also the interpretive ambiguity of where the line actually is when it isn't sharp. The Hanna instrument gives robust repeatable readings as long as you initially wait a few seconds for temperature stabilization. I'm definitely happy with this purchase.

A MUST Tool for all grain brewers
Works great, fast & extremely accurate. Would suggest this item to anyone who brews all grain beers. The precise ability to spot check your process is a real plus.
The new Hanna Digital Refractometer was another great addition to our home brewing system

Takes the guesswork out of the refractometer. Super easy to use.

A few drops does the trick
It works great but tet the sample cool a bit. Yes, it does account for temperature but I have found letting the sample sit on the glass for 45 seconds or so makes a significant difference in the reading and the final reading is more accurate (tends to be higher) when compared to a full hydrometer reading.

Great Product, Consistent Results
I originally purchased this because of all the 1 gallon sour experiments I am working on. A small sample (such as one drop) is all you need to get a reading, which can be quite useful when you have a small volume to take a sample from. I always keep a fresh bottle of distilled water nearby to zero in the device, and it always seems to work perfect. After using for a couple of months, and tons of samples, the only bad thing about this Hanna refractometer are the necessary conversions (you have to convert out of Brix and Celsius). When I originally purchased this refractometer I didn't trust it completely, but since I've verified results with a hydrometer many times and any small variation in results I can only assume is from my variation in reading the hydrometer. If and when this goes out, I'll probably just have to get another so I don't have to waste time with a hydrometer again!

Great - no more guessing!
I love having my readings in clear digital numbers and with temp so I can adjust gravity appropriately. Super easy to operate and a great addition to brew day!
