All new Specific Gravity Refractometer is an affordable way to take quick instant gravity readings. And now without Math!! 
The scale in the viewfinder reads 0-32% Brix scale and 1.000 to 1.120 SG. It comes with a foam lined hard shell case, an eye dropper for taking samples and instructions.
It is Automatic Temperature Compensating, so it will adjust automatically to the ambient temperature.

Note: Once calibrated with distilled water, the refractometer is accurate for taking your Original Gravity readings. Once fermentation has started, the alcohol created throws off the reflectivity in a measurable way. We have a handy calculator for convering your final gravity reading. Click here for calculator.
