Does anyone know if there is an anti freeze tester made specifically for boiler anti freeze (propylene glycol) or do you just get an automotive tester for the Sierra anti freeze used in cars?
 
There are test strips, which are probably the best way to go, for an end-user application.

There's also an optical tester, but they tend to be pretty expensive. The strips aren't cheap, but you're not exactly going to use many of them on a single system - the optical testers really only pay for themselves when you test a hundred systems a year, or somesuch...
