OAT Anti-Freeze Testing

Hi All

Another totally confusing topic with many different opinions on the internet. I have OAT coolant in my TF, and would like to establish its concentration rate. We all know it should be 50%

I have tried to locate an OAT tester but all I can find are those that test ethylene-glycol base anti-freeze. (except halfords cheap pocket tester which I am informed is also not accurate)

I am lead to believe that I cannot use a ethylene-glycol base anti-freeze tester as they are not accurate with OAT.

The only opion I have found is test strips.

Opinions please.

There are lots of reasonably priced refractometers on The Bay Of E that will read accurately all anti freeze mixtures.

OAT antifreeze is still ethylene glycol based so a standard tester is fine.
The OAT is merely anti corrosion additives in the Ethylene glycol.
