PCE Instruments PCE-DRW 2 Refractometer

Waterproof digital wine Refractometer PCE-DRW 2 Determination of sugar content in wine / Brix, Oechsle, KMW or alcohol content / ideal for winemakers / IP65 Protection / with automatic shut-off the digital wine refractometer from PCE Instruments was specially developed to determine the maturity of grapes in wine growing. The wine refractometer is used to precisely determine the sugar content in the must. In this way, the winemaker can effectively determine the potential alcoholic strength of the wine subsequently obtained from the grapes. Because the more mature a grape is, the more sugar it usually contains. This sugar is converted into alcohol during wine production. The wine refractometer is an instrument based on the measurement of the refractive index of a liquid. With the help of the wine refractometer, the user can measure the concentration of sugar in the grape must with a small sample quantity. It is sufficient to drizzle a few drops of grape must into the stainless steel cavity of the measuring device in order to obtain a meaningful result. A prism is enclosed in the sample well, so that the sugar concentration in the must is measured by refraction. On average, about 16.5 g sugar is equivalent to 1% alcohol. The integrated light source in the digital wine refractometer prevents measurement errors, which are quickly caused by artificial light such as fluorescent lamps in an analogueue wine refractometer. After automatic temperature compensation (10…40 °C), the measurement result is displayed quickly and precisely on the large, easy-to-read LC display of the wine refractometer. The user of the wine refractometer can choose between different, common measuring units: Brix (0 to 45.00 %), Oechsle (3 to 150), KMW (0 to 25.00) or alcohol content (0 to 22.00 %). In addition, the display provides information about the measured temperature of the liquid thanks to an integrated temperature display. The glass prism of the wine refractometer, which is enclosed in the stainless steel recess, can be cleaned easily and quickly before and after the measurement and is closed with a prism cover made of plastic. The manufacturer has designed the wine refractometer in such a way that the glass prism is protected from damage. The comfortable three-button operation guarantees a user-friendly handling and virtually eliminates the misuse of the wine refractometer. In order to conserve the battery of the measuring device, the manufacturer has equipped the wine refractometer with an automatic shut-off. When not in use, the wine refractometer switches off automatically after one minute. If necessary, the user can calibrate the wine refractometer himself at any time, in which he gives a few drops of distiled water into the measuring recess and triggers the calibration by pressing a button. Winzer Refractometer Applications A refractometer measures the concentration of dissolved substances in liquids. The PCE Instruments Wine Refractometer is an excellent tool for determining the maturity of grapes in seconds thanks to its user-friendly handling. Thanks to the handy design, the wine refractometer can be used anytime and anywhere. The robust and waterproof ABS housing of the Wein Refractometer is specially designed for outdoor use. Its simple operation and flexible application possibilities make the wine refractometer from PCE Instruments indispensable in the viticulture. The refractometer provides the winemaker with important decision-making aids within a very short time. With the wine refractometer, the winemaker can quickly determine the must weight, an important quality feature in wine growing, on site.
