Refractive Index is measured for many reasons and is useful for multiple applications. It is a parameter that provides valuable information into determining the concentration of liquid mixtures (i.e. any dissolved mixtures), as well as providing information as to a sample's purity and clarity. This is useful for identification and quality control purposes.


Many industries will use refractometers for quality control purposes, particularly within food and beverage industries, from portable handheld machines to bench top-based refractometers such as Abbe or automatic digital refractometers. Temperature controlled refractometers are ideal for high precision refractive index measurements. These are ideal for food, beverage, pharmaceutical, medical and petrochemical industries and applications.


Certificaciones: UKAS ISO 17025 and ISO 17034.
