Concentration Meters
Also known as refractometers, these measure concentration with two or three drops of a solution. Place your sample on the reflecting prism and look through the eyepiece to view the concentration on the internal scale.

For Testing Freezing Point—Concentration meters with freezing-point scale measure the freezing point of propylene glycol and ethylene glycol as well as the specific gravities of battery acids from 1.15 to 1.30.
Automatic Temperature Compensation (ATC) Range—Concentration meters with automatic temperature compensation standardize readings at 68° F to prevent inaccurate results in fluctuating temperatures.
