    refractometer

    use a refractometer.



    also a automotive antifreeze tester will get you close. but they are for ethylene glycol.



    heating system should have propylene glycol.

    Refractometers:

    And most Refractometers will do both kinds of anti-freeze and lead acid batteries.
