OPTi Digital Handheld Refractometer with a novel Selectable Scales Library

Digitial refractometers measure the degree at which the light changes' direction when passing through a sample.  This is called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established. This is then used in various industries to determine the concentration of a solution - the key to note is that the process is temperature-dependent. There are a number of digital refractors in the market that cater to all the different scales used in various industries.  A large majority use the Brix scale which is calibrated to the number of grams of cane sugar contained in 100 mL of water. The new OPTi Multiple Scale Digital Handheld Refractometer is designed to include the vast majority of currently used scales in one meter. This refractometer contains 3 active scales pre-loaded. These pre-set scales can be interchanged at any time by the user from an onboard library of 50 individual scales. Relating specifically to the Brix scale, the OPTi is the only refractometer to cover the full Brix range (0-95). The full list of onboard scales can be found below. Key features:
