Cheap but that works well. FWIW, there are types of refractometer that are totally unsuitable (a clinical refractometer, for example, which reads proteins in urine) and some that may be able to be made to work, but will require substantial extra effort and may or may not cover the right range (a Brix refractometer, for example).

Brix (Sugar) Scale.Refractometers are instruments used for measuring concentrations of aqueous solutions. A refractometer requires only a few drops of liquid. When light enters the liquid, the light changes directions. This is called a refraction. A refractometer measures the degree to which the light changes direction, called the angle of refraction.Choose from our selection of coolant-testing refractometers, including concentration meters, easy-read concentration meters, and more.
