Refractometer

Accurate, easy-to-use antifreeze testing instrument uses an adjustable eye piece to measure refracted light given off by all glycol-based antifreeze products, to determine the concentration of treatment present in the system

The refractive Index of a material is an optical measurement of its ability to bend a beam of light entering it. The refractive index may be used to determine the concentration of a material when dissolved in water, due to the difference in refractive index between water and the material being monitored. All glycol-based antifreezes will refract light and this property can be used to determine the concentration of treatment present
