Produktbeschreibung

Yieryi Hand Held Grape & Alcohol Wine Refractometer Professional PH Meter Digital Water Tester Wine Concentration Detector
TIPS
Due to the influence of air humidity, the value of the instrument appears is normal before use. Once calibrated with distilled water, it will return to normal
Feature of The Wine Refractometer：
Test the percentage level of Brix of grapes or other fresh fruit and determine crop ripening
Measure progress of fermentation in winemaking
Test the amount of sugar present and alcohol concentration in grapes
Helps winemaker know when fruit is at its peak of ripeness and should be harvested

Principle of technology
For example, a sugar meter mainly uses light to cause refraction when it enters another medium from one medium, and the ratio of the incident angle sine is always constant. This ratio is called the refractive index. The content of the soluble substance in the sugar solution is proportional to the refractive index in a normal environment, and the refractive index of the sugar solution can be determined, so that the sugar meter/refractometer calculates the concentration of the sugar.
Operation method: (The scale is used here as an example)
Place a few drops of the sample to be tested onto the main prism, close the daylight plate and check reading.Take the reading where the boundary line of blue and white cross the graduated scale. The scale will provide a direct reading of the concentration.
