Determine the refractive index everywhere Developed for a wide range of applications, ranging from c (more)hecking the sugar concentration in beverages to checking the hydrocarbon content of fuels, METTLER TOLEDO's line of portable refractometers provide accurate and repeatable results in seconds, displaying them in units of measurement appropriate. Portable digital refractometers can be used on a flat surface or dipped directly into the sample for quick and easy measurements. Accurate results During the measurement, Refracto automatically determines the temperature and corrects the refractive index back to a standard value of 20 ° C (or any user-defined temperature). This ensures accurate results, regardless of the ambient temperature. Clarity and simplicity The keyboard and menu structure make operation simple and efficient. The results are clearly displayed on the backlit LCD screen. The Refracto portable refractometer stores up to 1100 results and includes information such as sample ID, unit of measure, date and time and much more. Simple data management The measured values ​​can be viewed directly on the portable refractometer. Exporting results from Refracto to EasyDirect ™ refractometer and density meter software offers even more flexibility. With just a few clicks, you can review and filter results on your computer and create graphs to track samples over time and better control processes. Reports can be printed from the software or directly from the instrument.
