Refractometers

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.

The RE40D refractometers is used to easily determine the refractive index of liquids. The measuremen (more)ts are carried out using the total reflection method. With this method, even dark samples can be measured easily. Thanks to the latest technology – no moving parts, durable LED light source and resistant sapphire prism, the RE refractometers are virtually maintenance-free Measure liquids with a refractive index in a range from 1.32000 to 1.7000 Require a minimal amount of sample (approx. 0.4 milliliters) for the measurement Keep the temperature of the samples to be measured between  15.00 and 70.00°C thanks to a built-in Peltier thermostat (no water bath required) Calculate the refractive index of the samples for any reference temperatures based on user-defined temperature functions Show the refractive index of the samples directly in Brix degrees Able to convert the measured values into any units (e.g. Zeiss number) and display them directly in these units Suitable for concentration determinations. Concentrations are due to custom formulas or concentration tables are automatically calculated from the measured refractive index. Deliver statistical evaluations (mean value, standard deviation, relative standard deviation) of the results. Entry of 10 measurement methods. One of these methods is reserved for adjusting the device. Can be easily checked with the built-in check function.
