Refractometers

Refractometers and Polarimeters

Instruments designed to measure a sample's refractive index or polarization of light.

Typical uses for refractometers:

• Laboratory medicine: Used to measure total proteins in blood samples and specific gravity in urine samples
• Gemology: Used to identify gems
• Aquariums: Measure water salinity and specific gravity
• Industry: Measure coolant concentrations
• Homebrewing: Measure fermentable sugars that will be converted to alcohol
