Glycol refractometer
I have been using a sugar brix refractometer to check the freezing point of glycol and was always told between 15 -22 was the proper range. I just bought a glycol refractometer that will tell me the exact freezing point of the bath. Now I just need to know what the correct temp range I should be looking for. I usually have the glycol t-stat set for 28 degrees (F). I service many different accounts with different equipment so I am just looking for basic ranges.
