A refractometer is used to measure the density of a solution.
Measure the brix level (sugar level) in your grapes with just one drop! The perfect vineyard tool for monitoring ripening grapes. We also use them after the crush to get an exact brix reading. A refractometer cannot be directly used after fermentation has taken place as alcohol distorts the reading, however a conversion calculator (MS Excel based) is available from MoreWine! on request.
Refractometer Statistics: Our refractometer is hand held with a metal body, flexible eye piece and rubber grip. It features a 0 to 32% Brix scale with .2% resolution and ATC (Automatic Temperature Compensation). Traditional refractometers without ATC are calibrated to work at 68 degrees Fahrenheit. The ATC function allows you to use the refractometer in an ambient temperature range of 50-86 degrees Fahrenheit (10-30 Celsius.) Because your sample is just one drop, and will quickly adjust to the temperature of the refractometer, the temperature of the sample is irrelevant. Our unit also comes with a manual calibration knob that is secured with a lock nut. To calibrate place one drop of water (distilled water is preferred, but not required) on the testing platform and adjust to zero if necessary.
