$38 Brewing Refractometer - Dual Scale 0-32% Brix 1.000-1.120 Specific Gravity
Item Description: RSG-100ATC Portable Brix & Beer Wort Specific Gravity Refractometer (0-32% Brix & 1.000-1.120 Wort SG) with (10) 3ml Pipettes - In a SOFT CASE!
* 0-32% Brix Scale / 1.000-1.120 Wort Specific Gravity
* Accurate to +/- 0.20% Brix / +/- 0.001 Wort Specific Gravity
* Scale Divisions: 0.20% / 0.001 Wort Specific Gravity
* Automatic Temperature Compensation (ATC)
* Sturdy design, made of lightweight machined Aluminum, not "carbon" plastic
* Comes in a zipper SOFT CASE, with a calibration screwdriver, pipette and users guide
The RSG-100ATC use ambient light, no battery or power source is required. Models with the “ATC” suffix are equipped with “Automatic Temperature Compensation” for accurate measurements without recalibration after shifts in ambient working temperature (field use). You don't need a temperature correction chart if you take readings when the ambient air temp is between 50-86'F (10-30'C).
Included are: (10) pipettes for dropping test fluids onto the prism (never dip the refractometer into the test fluid!), a mini screwdriver for scale calibration, and a Users Guide. Comes in a zipper bag SOFT CASE.
BEER AND WINE MAKING INFORMATION:
Are you tired of not hitting your desired target gravities? Have you tried to cool a large sample so you could use a hydrometer and see what your gravity is? A refractometer allows you take instant gravities readings at any point during the boil, or run off from the mash. On the fly readings allow you to add more water or boil longer so you can attain exactly the gravity you desire or stop sparging before you extract tannins form the grain. Unlike a hydrometer, a refractometer is a simple solution requiring only a couple drops for a sample.
Refractometers measure degrees brix, which are nearly equivalent to Balling or Plato. A specific gravity scale for unfermented wort is also included. For reading once fermentation has started software programs like ProMash and BeerSmith are recommended.
Here’s how: A refractometer instantly reads gravity, in Brix, and specific gravity for unfermented wort by measuring the degree that light passing through the sample is bent. Refraction is what makes a pencil look bent when dipped in a glass of water. If you were to stick a pencil in a series of glasses holding increasingly concentrated sugar water, you would see the pencil apparently bends to a greater degree as the sugar content rises. A refractometer works on the same principal.
Easy to use: Apply 2-3 drops to the prism face, close cover and make sure the glass has no dry spots or air bubbles. Wait 30 seconds to allow the sample to come to ambient temperature. Look through the eyepiece while aiming your refractometer at a light source. The meter will show a line between blue and clear. This line will correspond with the brix scale on the side of the viewing screen.
To calibrate: Place one drop of distilled water on the prism face and turn the manual calibration screw to it reads 0 Brix if necessary.
