Brix refractometers are effective at measuring coolant concentration. Coolant’s primary purpose is to lubricate and cool the work surface and tooling. Each coolant works best for a given application at a recommended concentration of it to water. Monitor the initial coolant charge, then each day, as evaporation increases concentration at the sump level. Maintaining the recommended concentration is essential to prevent problems.
Check your coolant’s technical data sheet to determine where your coolant will read on the Brix Scale. Some have a “Refractometer Factor” which you multiply the scale reading by to obtain the value in percent.
Select a scale that will read your target value, but also higher values, due to evaporation at the sump level.

Glycol Refractometers for Automobile Coolants and Battery Acids
Zebra Glycol Refractometers have a temperature scale to read the protection rating of an ethylene and propylene glycol mixture as well as battery acids.
These units are pre-calibrated at the factory. To verify that it is calibrated you can put a few drops of water onto the lens, then close the lid. You should notice that the line reads just below the 30°F mark. This is the indication that it is reading correctly.
Once you have your glycol mixture ready place a few drops of it onto the lens. The line will indicate at what temperature your mixture will protect your equipment.
