The PTRP Prismatech refractometers are fully automatic portable digital refractometers with the highest level of accuracy of their kind. They are designed with a wide measurement range, measurement temperature range, and highest measurement accuracy, which are suitable for multiple sample types; such as measuring oils and fats with high melting points, aroma oils of high refractive index and organic solvents, meeting demands for high accuracy measurements. They also have a built-in Peltier thermo module for maintaining a constant sample temperature while taking measurements.
