RKI Instruments RI-257

The RKI Instruments RI-257 is the most advanced and versatile digital refractometer on the market. It features a wide measurement range (0-95% Brix), high accuracy (±0.1% Brix), and a large, easy-to-read display. The RI-257 also has a built-in temperature compensation system, which ensures accurate readings even when the temperature of the sample changes. What sets the RI-257 apart from competitors is its ability to measure the refractive index of both liquids and solids. This makes it ideal for a wide range of applications, including food and beverage testing, pharmaceutical manufacturing, and chemical analysis. The RI-257 is also the only digital refractometer on the market that can be used to measure the refractive index of opaque samples.
