VEE GEE® X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements. These wine and beer refractometers are an excellent way to measure the sugar content in your wort during the mash, pre-boil, and post-boil steps of the process.
Easy to Use
Operation consists of placing 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the readings.
The VEE GEE® exclusive Zero-Ring eliminates the hassle of using a separate tool for calibration. Simply place a few drops of distilled water or liquid standard (R.I. oil or prepared sucrose solution) on the prism, turn the built-in Zero-Ring until the shadow line is at the correct value of the liquid, and secure the set screw that’s it.
Featuring the largest, easiest-to-read scale available; with clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy even when several different operators use the instrument. Automatic Temperature Compensation frees the user from having to re-calibrate in work environments with large temperature swings. The effective compensation range is 50-86 F(10-30 C). All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors.
The X-Series models feature rugged construction to provide years of reliable use. The prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Also feature non-roll stands to ensure that once the units are placed on a table or bench top, they won’t be prone to roll off the surface.
Compact & Portable
The small size of the X-Series models allows them to be used anywhere the field, plant, or lab.

For me, getting a refractometer was one of those upgrades that made a lot of difference. With a refractometer you need a sample size of two drops. I figured that this would pay for itself in beer savings alone. I also had just broken my hydrometer and came to the realization that hydrometers are made of breakable glass that can break! 🙂
Refractometers can be used to measure gravity throughout the brewing process. You can also estimate the alcohol content of your beer if you forget to take an OG with the use of a refractometer and a hydrometer. Check out Sean Terrill’s excellent refractometer calculator.
