The HI 96811 Digital Wine Refractometer is rugged, lightweight and waterproof for measurements in the lab or field.
This optical instrument employs the measurement of the refractive index to determine parameters pertinent to the wine industry.
The actual measurement of the refractive index is simple and quick and provides the vintner a standard accepted method for sugar content analysis. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds, the instrument measures the refractive index of the grape must. These digital refractometers eliminate the uncertainty associated with mechanical refractometers and are ideal for fast, reliable measurements in the field.
HI 96811 converts the refractive index of the sample to sucrose concentration in units of percent by weight, %Brix (also referred to as °Brix). The conversion used is based on the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Since the majority of sugar in grape juice is fructose and glucose and not sucrose, the reading is sometimes referred to as “Apparent Brix”.

This product seems fine-- but it says in the description that it's waterproof. It is NOT WATERPROOF-- as the booklet says clearly.Also, you need your own pipettes (plastic) as this product doesn't come with any. It includes a cheap 9v battery but that's it. Get your mitts on some distilled water to do the calibrations. And, you'll need to have some guide to help you determine what the brix % means if you're a newbie at this (like I am). I hoped there would be some explanation of the information-- but alas, nope. At least the machine does the calculations for me & there's no fiddling with the manual refractometers. Otherwise, it's as described.

With the broad spectrum of refractometers, this one falls comfortably in the middle. The lower-end optical products are harder to use, and less accurate. The much higher end products are all digital and can cost hundreds and even thousands of dollars. For most consumers, gardeners, and even small-scale professional wine and beer enthusiasts this product works great and is a perfect balance of price and quality.

Hanna Instruments HI 96811 Brix Refractometer 0-50% works well. I am using it for my vegetable garden determining the nutritional value of my food. This instrument helps me defined which practices in the garden are working better than others.The machine was simple to use and clean. It came with good instructions as well.

Great device. I really appreciate taking the guesswork or observers bias out the measurements normally obtained from eyeball-driven refractomers. Unit is simple, easy to calibrate, and extremely repeatable. Clear digital display, easy to clean, sturdy piece of equipment.
