Interesting didn't know about this but found this thru Google
0.2 V to 0.5 V - antifreeze is still good
0.5 V to 0.7 V - antifreeze is borderline
0.7 V or greater - antifreeze is unacceptable.

The best way to test long life coolants that I know of is to use Acustrip 1550 three way test strips, specifically for coolants like DEXCOOL. These test strips are simple to use and in one test will give you freeze protection, reserve alkalinity, and PH.
acustrip.com I think.
You can have plenty of freeze protection yet still have coolant that is old, contaminated and corrosive. These strips, used like a litmus test, will tell you if it needs to be changed.
The way coolant usually gets acidic and corrosive is that over time, molecules of carbon dioxide from the combustion process make their way past the head gasket into the coolant. Water and carbon dioxide form carbonic acid, which is corrosive.
