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.

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!

I love this thing
I converted to refractometers a while ago, which I love due to their ability to measure small samples, which you can cool quickly. However, reading a handheld one, especially with glasses on, felt like an exercise in subjectivity. We would pass it around, trying to get everyone's vote. When I damaged it, I considered buying another. But I was at MoreBeer during a sale, and this was slightly less exorbitantly priced, and I decided to get it. I am so glad I did. This is so clear and consistent to get a reading.

Small Sample Size
Temperature Conversion
Easy to read

Annoying to clean (I swipe with paper towel, I add a few drops of water, swipe again)
Doesn't list SG/Plato/ABV
Not cheap

A dream to work with!
Let's cut to the chase; the only issues with this refractometer are the lack of internal conversion to Plato, Specific Gravity, or just plain ABV.
It's very simple to calibrate and use repeatedly. The automatic temp correction takes guess work out of the equation.
With a quick conversion table check, very accurate readings are at your fingertips!
While the price is high, it is easily one of the best additions to the brewery and coupled with the ease of use, it really is an invaluable addition to the brewery.

Easy and accurate gravity readings!
This is a great product to ease any brew day. I can take gravity readings at pre-boil and post boil to ensure I hit my targets instantly due to the temperature correction on the device. The cleanup is extremely easy, two wipes of paper towels then put it away. I keep a Brix-SG conversion chart nearby so I can translate the readings to my brewing logs.
