How to Convert Refractometer Glycol Freeze-Point Readings into Percent Concentration.

I have some questions about your 7084VP+ MISCO glycol and battery tester. How would I use this refractometer to verify a 30% glycol solution in one of our systems since the unit it reads are in degrees Fahrenheit?

You have two choices. First, ask your glycol supplier for a chart of glycol concentration to freeze point. They will be happy to supply you with one. Then measure the freeze point of the fluid with the 7084VP+ and look up the percent concentration corresponding to your freeze point measurement.
