This popular general purpose refractometer gives a wide refractive indexes (RI) and temperature ranges making it ideal for applications in the essential oil, crude oil, and edible oil industries. The GPR 12-70 is also perfect for measuring sugars, fruit juices, drinks, solvents, thick pastes pharmaceutical products, plastics, and any other product which requires quality control for RI or concentration. Also, this instrument includes improved software, can be measured up to 70°C, contains synthetic sapphire prism and LED light source for long life, is less than 24cm wide, has a waterproof construction which was designed for easy cleaning, and includes many more handy features and accessories.

We now offer a higher accuracy general purpose instrument with similar features to our popular GPR 12-70 refractometer. The GPR 53X offers a 5th decimal place resolution of Refractive Index (RI) and a 2nd decimal place resolution of Brix (% of sucrose). This model covers the full Brix range required by the sugar industry (0 to 95%). The GPR 53X also comes with the latest software that includes intelligent monitoring of when the sample reading has reached stability, sample numbering and time, date and serial number output for traceability, and more. More features include a user friendly 16 button keypad, a waterproof construction which was designed for easy cleaning, a compact design with a small footprint (less than 24cm wide), a wide temperature range (5°C up to 70°C), contains synthetic sapphire prism and LED light source for long life, and includes many more handy features.
