*Check coolant product data to determine how your coolant will read on the Brix Scale.

Refractometers Measure Concentration & Oil Emulsion Concentration is the position of the horizontal line on the brix scale and is shown in the diagram below. Oil emulsion is signified by the blurriness of that line and is shown in the diagram above. As tramp oils are beaten into the coolant, the line will become blurrier. When the line is so blurry that an actual line is not visible, it is time to change the coolant.
