The Lovibond® Brix and Glycol series of refractometers are convenient, fast and accurate and offer no-mess, instant results. They provide automatic temperature compensation and direct readings of freeze points and concentration (Ethylene Glycol & Propylene Glycol).
The Lovibond® Glycol Refractometer offers a convenient, fast and accurate way to assess the glycol concentration of engine coolants and other anti-freeze solutions. This easy-to-use optical instrument provides a no-mess, instant result that is impossible to achieve using traditional hydrometer based methods. Automatic temperature compensation provides immediate, accurate and direct readings without the need to measure temperature or apply a correction factor. The refractometer scale provides direct readings of freeze points and concentration of Ethylene Glycol and Propylene Glycol.
